Glucagon-like peptide-1 receptor (GLP1R) is a 7-transmembrane receptor protein found on beta cells of the pancreas. It functions as a receptor for glucagon-like peptide 1 (GLP-1) hormone, which stimulates glucose-induced insulin secretion. GLP1R functions at the cell surface and becomes internalised in response to GLP-1 and GLP-1 analogs, playing an important role in the signalling cascades leading to insulin secretion. It is a member of the glucagon receptor family of G protein-coupled receptors [1]. GLP1R is composed of two domains, an extracellular domain that binds the C-terminal helix of GLP-1 [2], and a transmembrane domain [3] that binds the N-terminal region of GLP-1 [4][5][6].
GLP1R also displays neuroprotective effects in animal models. Polymorphisms in this gene are associated with diabetes, making it an important drug target for the treatment of type 2 diabetes. Alternative splicing of the GLP1R gene results in multiple transcript variants.

Fragile X Mental Retardation 1 (FRM1) is an RNA binding protein that plays a central role in neuronal development and synaptic plasticity through the regulation of alternative mRNA splicing, mRNA stability, mRNA dendritic transport and postsynaptic local protein synthesis of a subset of mRNAs.
A trinucleotide repeat (CGG) in the gene encoding this protein is normally found at 6-53 copies, but an expansion to 55-230 repeats is the cause of fragile X syndrome. Expansion of the trinucleotide repeat may also cause one form of premature ovarian failure (POF1). Multiple alternatively spliced transcript variants that encode different protein isoforms and which are located in different cellular locations have also been described for this gene.
FRM1 has been shown to play a translation-independent role in the modulation of presynaptic action potential (AP) duration and neurotransmitter release via large-conductance calcium-activated potassium (BK) channels in hippocampal and cortical excitatory neurons [1]. FMR1 may be involved in the control of DNA damage response (DDR) mechanisms through the regulation of ATR-dependent signaling pathways such as histone H2AFX/H2A.x and BRCA1 phosphorylations [2].

Ubiquilin-2 (UBQLN2) is a 624-amino acid multi-domain adaptor protein and a member of the ubiquilin family of proteins that regulate the degradation of ubiquitinated proteins by the ubiquitin-proteasome system (UPS), autophagy and the endoplasmic reticulum-associated protein degradation (ERAD) pathway. Ubiquilins are characterised by the presence of an N-terminal ubiquitin-like domain and a C-terminal ubiquitin-associated domain. The central portion is highly variable.
UBQLN2 Mediates the proteasomal targeting of misfolded or accumulated proteins for degradation by binding to their polyubiquitin chains, through the ubiquitin-associated domain (UBA) and by interacting with the subunits of the proteasome through the ubiquitin-like domain (ULD).
Mutations in UBQLN2 are associated with Amyotrophic Lateral Sclerosis with most ALS-linked mutations localised to the proline-rich repeat (Pxx) region that is unique to ubiquilin-2 and not present in the other members of the ubiquilin protein family. UBQLN2 has also been shown to bind the ATPase domain of the Hsp70-like Stch protein. Mutations in UBQLN2 are also observed in familial ALS (FALS) cases associated with aberrant TDP-43 inclusions.

Optineurin (OPTN) is an autophagy receptor that interacts with numerous proteins. It is involved in regulating many cellular functions, including vesicular trafficking from the Golgi to plasma membrane, endocytic trafficking, and signaling leading to NF-kappa-B (see 164011) activation [1]
Optineurin has been shown to interact with huntingtin [2], transcription factor IIIA [3], and RAB8 [4] and may therefore function in cellular morphogenesis and membrane trafficking, vesicle trafficking, and transcription activation. Alternative splicing of the gene results in multiple transcript variants encoding the same protein.
Optineurin mutations are associated with Glaucoma and Amyotrophic lateral sclerosis (ALS).

The human TREM2 kit is a sandwich ELISA. The capture antibody is a mouse monoclonal TREM2 antibody pre-coated onto the 96-well strip plates provided in the kit. Human test samples and standards of known TREM2 concentration are added to these wells and allowed to complex with the bound TREM2 antibody. A biotinylated goat polyclonal TREM2 antibody is then added. This detection antibody binds to the antigen thus completing the sandwich. After washing, an enzyme Avidin-Biotin-Peroxidase complex (ABC) is added which binds to the second antibody. The peroxidase substrate TMB is added to induce a coloured reaction product. The intensity of this coloured product is directly proportional to the concentration of TREM2 present in the samples. The purpose of this kit is the in-vitro quantitative determination of human TREM2 in samples such as sera, plasma (heparin, EDTA), and cell culture supernates. This kit has been configured for research use only and is not to be used in diagnostic or clinical procedures.
Background Info:
The protein Triggering receptor expressed on myeloid cells 2 (TREM2) forms a receptor signaling complex with the TYRO protein tyrosine kinase binding protein (TYROBP). TREM2 has roles in the immune response and may be involved in chronic inflammation by triggering the production of constitutive inflammatory cytokines. Defects in this gene are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL). Alternative splicing results in multiple transcript variants encoding isoforms with differing subcellular locations.

The purpose of this kit is the in-vitro quantitative determination of human TREM2 in samples such as sera, plasma (heparin, EDTA), and cell culture supernates. This kit has been configured for research use only and is not to be used in diagnostic or clinical procedures.
Background Info:
The protein Triggering receptor expressed on myeloid cells 2 (TREM2) forms a receptor signaling complex with the TYROprotein tyrosine kinase binding protein (TYROBP). TREM2 has roles in the immune response and may be involved in chronic inflammation by triggering the production of constitutive inflammatory cytokines. Defects in this gene are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL). Alternative splicing results in multiple transcript variants encoding isoforms with differing subcellular locations.

FUNCTION: Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization. SUBCELLULAR LOCATION: Cytoplasm; cytosol. Cell membrane. Mostly found in the axons of neurons, in the cytosol and in association with plasma membrane components. ALTERNATIVE PRODUCTS: 8 named isoforms produced by alternative splicing. Additional isoforms seem to exist. Isoforms differ from each other by the presence or absence of up to 5 of the 15 exons. One of these optional exons contains the additional tau/MAP repeat. TISSUE SPECIFICITY: Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system. DEVELOPMENTAL STAGE: Four-repeat (type II) tau is expressed in an adult-specific manner and is not found in fetal brain, whereas three-repeat (type I) tau is found in both adult and fetal brain. DOMAIN: The tau/MAP repeat binds to tubulin. In Alzheimer disease, the neuronal cytoskeleton in the brain is progressively disrupted and replaced by tangles of paired helical filaments and straight filaments, mainly composed of hyperphosphorylated forms of Microtubule-associated protein Tau. Defects in Microtubule-associated protein Tau are a cause of frontotemporal dementia and parkinsonism linked to chromosome 17, as well as a number of other neurodegenerative diseases.

Apolipoprotein E (ApoE) is a lipoprotein involved in fat metabolism and acts as cholesterol carrier between cells and across tissues. On a genetic level, three APOE alleles are described, APOE2, APOE3 and APOE4. These alleles give rise to six APOE isoforms, which are differentially implicated in various diseases. In the peripheral system, APOE4 is linked to increased risk of atherosclerosis. In the CNS, the ability of APOE4 in clearing beta-amyloid is impaired, while APOE3 and APOE2 are more efficient in performing this task. The APOE4 genotype in particular has been linked to increased risk for developing Alzheimer's Disease.

Ubiquitin is a highly conserved 76 amino acid protein with an estimated molecular weight of 8.56 kDa which has a central role in regulated protein degradation. It is a protein modifier which can be covalently attached to target lysines either as a monomer or as a lysine-linked polymer. Several types of polymeric chains can be formed depending on the lysine used for the assembly. Attachment to proteins as a polymer leads to their degradation by the 26S proteosome; a complex, multicatalytic cytosolic and nuclear protease. Attachment to proteins as a monomer or as an alternatively linked polymer does not lead to proteasomal degradation and may be required for numerous functions, including maintenance of chromatic structure, regulation of gene expression, stress response, ribosome biogenesis and DNA repair. Ubiquitin is synthesized as a polyubiquitin precursor with exact head to tail repeats, the number of repeats of which differ between species and strains. In some species there is a final amino-acid after the last repeat, here in bovine a Cys. Some ubiquitin genes contain a single copy of ubiquitin fused to a ribosomal protein (either L40 or S27a).

The amyloid beta peptide is derived from the cleavage of the Amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. However, the form(s) of amyloid-beta peptide (A?) associated with the pathology characteristic of Alzheimer's disease (AD) remains unclear. In particular, the neurotoxicity of intraneuronal A? accumulation is an area of considerable research and controversy principally because antibodies thought to be specific for A? have been shown to actually detect intraneuronal APP and not A? exclusively.MOAB-2 (mouse IgG2b) is a pan-specific, high-titer antibody to A? residues 1-4 as demonstrated by biochemical and immunohistochemical analyses (IHC), and is highly specific just to amyloid beta peptide.MOAB-2 did not detect APP or APP-CTFs in cell culture media/lysates (HEK-APPSwe or HEK APPSwe/BACE1) or in brain homogenates from transgenic mice expressing 5 familial AD (FAD) mutation (5xFAD mice). Using IHC on 5xFAD brain tissue, MOAB-2 immunoreactivity co-localized with C-terminal antibodies specific for A?40 and A?42. MOAB-2 did not co-localize with either N- or C-terminal antibodies to APP. In addition, no MOAB-2-immunreactivity was observed in the brains of 5xFAD/BACE-/- mice, although significant amounts of APP were detected by N- and C-terminal antibodies to APP, as well as by 6E10.In both 5xFAD and 3xTg mouse brain tissue, MOAB-2 co-localized with cathepsin-D, a marker for acidic organelles, further evidence for intraneuronal A?, distinct from A? associated with the cell membrane. MOAB-2 demonstrated strong intraneuronal and extra-cellular immunoreactivity in 5xFAD and 3xTg mouse brain tissues.

Western Blotting (WB), Immunohistochemistry (IH), Immunohistochemistry/paraffin embedded IH(P), Immunoprecipitation (IP), Immunofluorescence (IF), ELISA.Antibody has been tested in WB using purified synthetic beta-amyloid preparations and from transgenic mouse brain formic acid extracts (see figure 1). Formic acid extraction/concentration is required for western blot detection from extracts. MOAB-2 antibody is specific for beta-amyloid and does not detect APP. Suggested dilution of 1:2000-1:5,000 for WB, standard ECL detection systems. Tissue samples for the detection of beta-amyloid should be prepared as detailed in K.L. Youmans et al. {Journal of Neuroscience Methods 196 (2011) 5159} for best results. Detection of beta-amyloid 40/42 in direct westerns can be difficult; Dot-blots of prepared samples are recommended as detailed in Youmans. KL et al 2012. IR or fluorescent detection systems not yet tested, they but are expected to work well with higher primary antibody dilutions because of the increased sensitivity of the detection methods.Suggested dilutions for IHC are 1:50-1:1,000. Fresh frozen, 4% paraformaldehyde fixed frozen, or formalin fixed paraffin embedded tissues are all suitable. Optimal dilutions must be determined by the end user. Antigen retrieval is required in fixed tissues for optimal staining.Antibody was tested on 4% paraformaldehyde/0.1% glutaraldehyde fixed frozen tissue from 3xTg and 5xFAD mice. MOAB-2 antibody detects intraneuronal and extracellular beta-amyloid in IHC and does not detect APP {Youmans KL et al 2012}. The antibody also reacts with archival formalin-fixed, paraffin-embedded tissue samples with antigen Heat Induced Epitope Retrieval (HIER): Recommended Citrate, pH 6.0 buffer for HIER. Signal was weak without antigen retrieval. Immunoreactively was expressed in intraneural-amyloid deposition (plaque) in Alzheimer's brain. MoAB-2 was found to be extremely clean and with an excellent signal to noise ratio with no neuro-cellular diffusive staining.In addition MOAB-2 demonstrated no significant differences in A? detection using paraffin fixed, free-floating sections {Youmans KL et al 2012}. Formic acid (FA) treatment resulted in optimal detection of both intraneuronal and extracellular A? compared to without FA (incubated in 88% FA 8 min, Youmans KL et al 2012). Free floating tissue sections were permeabilized in TBS containing 0.25% Triton X-100 (TBSX; 3 Ã 10 min), blocked with 3% horse serum in TBSX (3 Ã 10 min) followed by 1% horse serum in TBSX (2 Ã10 min) and incubated with appropriate primary antibodies diluted in TBSX containing 1% horse serum overnight. See Youmans KL et al 2012 for full IH(P) protocol and method details. For IF, suggested dilution is 1:100-1:500. The antibody was tested on 4% PFA fixed frozen tissue. Fixed tissues were washed in TBS (3 Ã 10 min), then incubated in 88% FA (8 min), and then permeabilized in TBSX (3 Ã 10 min), and blocked in TBSX containing 5% bovine serum albumin (BSA; 1 hr). Sections were subsequently incubated with appropriate primary antibodies diluted in TBSX containing 2% BSA overnight on an oscillatory rotator. Detection was via fluorescently labelled absorbed secondary antibodies {Youmans KL et al 2012}.For IP, the suggested dilution is 1:200 to 1:1,000 for labeled beta-amyloid using Protein A/G conjugated beads as the capture vehicle {Youmans KL et al 2012}.In an ELISA, a dilution of 1:50-1:1000 is suggested. The antibody has been tested in ELISAs on synthetic beta-amyloid and tissue homogenates from beta-amyloid-Tg mice. Biosensis recommends optimal dilutions/concentrations should be determined by the end user for all applications. Dilutions provided are only meant to serve as a basic guide.

MOAB-2 detects preparations enriched in U-, O-, F-A?42, and U-A?40 by dot-blot, and is thus a pan-specific A? antibody. However, MOAB-2 is selective for the more neurotoxic A?42 compared to A?40. Indeed, MOAB-2 demonstrated a titration against antigen concentration, and detects A?40 at 2.5 pmol but U-, O- and FA?b42 at antigen concentrations as low as ~ 0.1 pmol {Youmans. KL et al 2012}. MOAB-2 does not detect APP (Amyloid precursor protein). | Human, Rat, other species not yet tested.By Dot blot, MOAB-2 detected rat A?40 and human A?40, albeit with less affinity than for A?42. {Youmans.

Visinin (sometimes known as hippocalcin-like protein 3, HLP3, HPCAL3, HUVISL1, VLP-1, VILIP and VILIP-1) was originally isolated biochemically from chicken retina as a major protein of about 24kDa on SDS-PAGE (1). Following cloning and sequencing of visinin, several visinin like proteins were discovered by homology screening (2, 3). One of these, Visinin-like protein 1 is a small Calcium binding protein which is very abundant in the nervous system and is found only in neurons, though different neurons have different levels of expression (4, 5). It is particularly concentrated in cerebellar Purkinje cells, and tends to be most abundant in perikarya and dendrites. The protein belongs to the large superfamLy of calmodulin and paravalbumin type proteins which function by binding Calcium ions. Calcium binding alters the confomation of these proteins and allow them to interact with other binding partners, the properties of which they may alter. Visinin-like protein 1 has four "EF hand" domains, which are negatively charged helix-turn-helix peptides which are responsible for Calcium binding. Visinin-like protein 1 is 191 amino acids in size and has a molecular weight on SDS-PAGE of 22kDa. The protein has recently been suggested to be a useful biomarker of Alzheimer's disease and traumatic brain injury (6, 7, 8).

FUNCTION: Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization. SUBCELLULAR LOCATION: Cytoplasm; cytosol. Cell membrane. Mostly found in the axons of neurons, in the cytosol and in association with plasma membrane components. ALTERNATIVE PRODUCTS: 8 named isoforms produced by alternative splicing. Additional isoforms seem to exist. Isoforms differ from each other by the presence or absence of up to 5 of the 15 exons. One of these optional exons contains the additional tau/MAP repeat. TISSUE SPECIFICITY: Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system. DEVELOPMENTAL STAGE: Four-repeat (type II) tau is expressed in an adult-specific manner and is not found in fetal brain, whereas three-repeat (type I) tau is found in both adult and fetal brain. DOMAIN: The tau/MAP repeat binds to tubulin. In Alzheimer disease, the neuronal cytoskeleton in the brain is progressively disrupted and replaced by tangles of paired helical filaments and straight filaments, mainly composed of hyperphosphorylated forms of Microtubule-associated protein Tau. Defects in Microtubule-associated protein Tau are a cause of frontotemporal dementia and parkinsonism linked to chromosome 17, as well as a number of other neurodegenerative diseases.

The amyloid beta peptide is derived from the cleavage of the Amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. However, the form(s) of amyloid-beta peptide (A?) associated with the pathology characteristic of Alzheimer's disease (AD) remains unclear. In particular, the neurotoxicity of intraneuronal A? accumulation is an area of considerable research and controversy principally because antibodies thought to be specific for A? have been shown to actually detect intraneuronal APP and not A? exclusively.MOAB-2 (mouse IgG2b) is a pan-specific, high-titer antibody to A? residues 1-4 as demonstrated by biochemical and immunohistochemical analyses (IHC), and is highly specific just to amyloid beta peptide. MOAB-2 did not detect APP or APP-CTFs in cell culture media/lysates (HEK-APPSwe or HEK APPSwe/BACE1) or in brain homogenates from transgenic mice expressing 5 familial AD (FAD) mutation (5xFAD mice). Using IHC on 5xFAD brain tissue, MOAB-2 immunoreactivity co-localized with C-terminal antibodies specific for A?40 and A?42. MOAB-2 did not co-localize with either N- or C-terminal antibodies to APP. In addition, no MOAB-2-immunreactivity was observed in the brains of 5xFAD/BACE-/- mice, although significant amounts of APP were detected by N- and C-terminal antibodies to APP, as well as by 6E10. In both 5xFAD and 3xTg mouse brain tissue, MOAB-2 co-localized with cathepsin-D, a marker for acidic organelles, further evidence for intraneuronal A?, distinct from A? associated with the cell membrane. MOAB-2 demonstrated strong intraneuronal and extra-cellular immunoreactivity in 5xFAD and 3xTg mouse brain tissues.Biosensis now offers biotinylated MOAB-2 antibody allowing more flexibility in experimental design by using the biotin-avidin/streptavidin detection method. Biotinylated MOAB-2 antibody may also help to reduce background staining in difficult-to-stain tissues and increase detection sensitivity. The ability of biotinylated MOAB-2 antibody to detect amyloid beta has been validated by IHC.Purified, non-biotinylated MOAB-2 antibody is available here.

The biotinylated MOAB-2 antibody has been tested by IHC (1:500 1:2,000 dilution) and is also expected to work in applications validated for the unlabelled antibody (M-1586-100) at same or higher dilutions: Western Blotting (WB), Immunohistochemistry (IHC), Immunohistochemistry/paraffin embedded IHC(P), Immunoprecipitation (IP), Immunofluorescence (IF), ELISA.Western Blotting:MOAB-2 has been tested in WB using purified synthetic beta-amyloid preparations and from transgenic mouse brain formic acid extracts (see Figure 1). Formic acid extraction/concentration is required for western blot detection from extracts. Suggested dilution of 1:2000-1:5,000 for WB, standard ECL detection systems. Tissue samples for the detection of beta-amyloid should be prepared as detailed in Youmans KL et al., 2011 (Journal of Neuroscience Methods 196: 5159) for best results. Detection of beta-amyloid 40/42 in direct westerns can be difficult; Dot-blots of prepared samples are recommended as detailed in Youmans KL et al., 2012. Immunohistochemistry:Suggested dilution for biotinylated MOAB-2 in IHC is 1:500-1:2,000. Fresh frozen, 4% paraformaldehyde fixed frozen, or formalin fixed paraffin embedded tissues are all suitable. Antigen retrieval is required in fixed tissues for optimal staining.Antibody was tested on 4% paraformaldehyde/0.1% glutaraldehyde fixed frozen tissue from 3xTg and 5xFAD mice. MOAB-2 antibody detects intraneuronal and extracellular beta-amyloid in IHC and does not detect APP (Youmans KL et al., 2012).The antibody also reacts with archival formalin-fixed, paraffin-embedded tissue samples with antigen Heat Induced Epitope Retrieval (HIER). Recommended buffer for HIER is citrate, pH 6.0. Signal was weak without antigen retrieval. Immunoreactivity was observed in intraneural-amyloid deposition (plaque) in Alzheimer's brain. MOAB-2 was found to be extremely clean and with an excellent signal to noise ratio with no neuro-cellular diffusive staining.In addition, MOAB-2 demonstrated no significant differences in A? detection using paraffin fixed, free-floating sections (Youmans KL et al., 2012). Formic acid (FA) treatment resulted in optimal detection of both intraneuronal and extracellular A? compared to without FA (incubated in 88% FA 8 min, Youmans KL et al., 2012). Free floating tissue sections were permeabilized in TBS containing 0.25% Triton X-100 (TBSX; 3 Ã 10 min), blocked with 3% horse serum in TBSX (3 Ã 10 min) followed by 1% horse serum in TBSX (2 Ã10 min) and incubated with appropriate primary antibodies diluted in TBSX containing 1% horse serum overnight. See Youmans KL et al., 2012, for full IHC(P) protocol and method details.Immunofluorescence:For IF, suggested dilution is 1:100-1:500. The antibody was tested on 4% PFA fixed frozen tissue. Fixed tissues were washed in TBS (3 Ã 10 min), then incubated in 88% FA (8 min), and then permeabilized in TBSX (3 Ã 10 min), and blocked in TBSX containing 5% bovine serum albumin (BSA; 1 hr). Sections were subsequently incubated with appropriate primary antibodies diluted in TBSX containing 2% BSA overnight on an oscillatory rotator. Detection was via fluorescently labelled absorbed secondary antibodies (Youmans KL et al., 2012).Immunoprecipitation:For IP, the suggested dilution is 1:200 to 1:1,000 for labelled beta-amyloid using SA-coated beads as the capture vehicle, similar to the protocols employed by Youmans KL et al., 2012.ELISA:In an ELISA, a dilution of 1:50-1:1,000 is suggested. The antibody has been tested in ELISAs on synthetic beta-amyloid and tissue homogenates from beta-amyloid-Tg mice. Biosensis recommends optimal dilutions/concentrations should be determined by the end user for all applications. Dilutions provided are only meant to serve as a basic guide.

Specificity:
MOAB-2 detects preparations enriched in U-, O-, F-A?42, and U-A?40 by dot-blot, and is thus a pan-specific A? antibody. However, MOAB-2 is selective for the more neurotoxic A?42 compared to A?40. Indeed, MOAB-2 demonstrated a titration against antigen concentration, and detects A?40 at 2.5 pmol, but U-, O- and F-A?b42 at antigen concentrations as low as ~ 0.1 pmol (Youmans. KL et al., 2012; PMID: 22423893). MOAB-2 does not detect APP (Amyloid Precursor Protein). | Human, rat, other species not yet tested. By Dot Blot, MOAB-2 detected rat A?40 and human A?40, albeit with less affinity than for A?42 (Youmans KL et al., 2012).

Siah-1 is a member of the seven in absentia homolog (SIAH) family. It is a E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins, including many proteins involved in transcription regulation, a cell surface receptor (DCC), cytoplasmic signal transduction molecules, an antiapoptotic protein (BAG1), a microtubule motor protein (KIF22), a protein involved in synaptic vesicle function in neurons (SYP) and a structural protein. Consequently Siah-1 is involved in many cellular processes such as apoptosis, tumor suppression, cell cycle, axon guidance, transcription regulation, spermatogenesis, and TNF-alpha signaling. It is predominantly a cytoplasmic protein but is also partially a nuclear protein. It is widely expressed at low levels and is down-regulated in advanced hepatocellular carcinomas.

FUNCTION: Functions as a cell surface receptor and performs physiological functions on the surface of neurons relevant to neurite growth, neuronal adhesion and axonogenesis. Involved in cell mobility and transcription regulation through protein-protein interactions. Can promote transcription activation through binding to APBB1/Tip60 and inhibit Notch signaling through interaction with Numb. Couples to apoptosis-inducing pathways such as those mediated by G(O) and JIP. Inhibits G(o) alpha ATPase activity. Acts as a kinesin I membrane receptor, mediating the axonal transport of beta-secretase and presenilin 1. May be involved in copper homeostasis/oxidative stress through copper ion reduction. Can regulate neurite outgrowth through binding to components of the extracellular matrix such as heparin and collagen I and IV. FUNCTION: Beta-amyloid peptides are lipophilic metal chelators with metal-reducing activity. Bind transient metals such as copper, zinc and iron. Rat and mouse beta-amyloid peptides bind only weakly transient metals and have little reducing activity due to substitutions of transient metal chelating residues. Beta-APP42 may activate mononuclear phagocytes in the brain and elicit inflammatory responses. Promotes both tau aggregation and TPK II-mediated phosphorylation (By similarity). FUNCTION: The gamma-CTF peptides as well as the caspase-cleaved peptides, including C31, are potent enhancers of neuronal apoptosis. SUBUNIT: Binds, via its C-terminus, to the PID domain of several cytoplasmic proteins, including APBB family members, the APBA family, MAPK8IP1, SHC1, Numb and Dab1. Binding to Dab1 inhibits its serine phosphorylation. Also interacts with GPCR-like protein BPP, FPRL1, APPBP1, IB1, KNS2 (via its TPR domains), APPBP2 (via BaSS) and DDB1. In vitro, it binds MAPT via the MT-binding domains. Associates with microtubules in the presence of ATP and in a kinesin-dependent manner. Interacts, through a C-terminal domain, with GNAO1. Amyloid beta-42 binds CHRNA7 in hippocampal neurons. Beta-amyloid associates with HADH2. TISSUE SPECIFICITY: different isoforms in different tissues: kidney. brain. liver. hippocampus, substania nigra pars compacta and cerebellum. In the cerebellum, all the isoforms are abundantly expressed in Purkinje cells.

Alpha synuclein is an abundant 140 amino acid neuronal protein, expressed primarily at presynaptic terminals in the central nervous system. FUNCTION: May be involved in the regulation of dopamine release and transport. Soluble protein, normally localized primarily at the presynaptic region of axons, which can form filamentous aggregates that are the major non amyloid component of intracellular inclusions in several neurodegenerative diseases (synucleinopathies). Induces fibrillization of microtubule-associated protein tau. Reduces neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase 3 activation. TISSUE SPECIFICITY: Expressed principally in brain but is also expressed in low concentrations in all tissues examined except in liver. Concentrated in presynaptic nerve terminals.SUBUNIT: Soluble monomer which can form filamentous aggregates. Interacts with UCHL1. Interacts with phospholipase D and histones. SUBCELLULAR LOCATION: Cytoplasm. Membrane. Nucleus. Note=Membrane-bound in dopaminergic neurons. Also found in the nucleus. ALTERNATIVE PRODUCTS: 3 named isoforms produced by alternative splicing.

FUNCTION: Functions within a multiprotein E3 ubiquitin ligase complex, catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins. These substrates include SYT11, CCNE1, GPR37, STUB1, a 22 kDa O-linked glycosylated isoform of SNCAIP and SEPT5. May play a more general role in the ubiquitin proteasomal pathway by participating in the removal and/or detoxification of abnormally folded or damaged protein. Loss of this ubiquitin ligase activity appears to be the mechanism underlying pathogenesis of PARK2. May protect neurons against alpha synuclein toxicity, proteasomal dysfunction, GPR37 accumulation, and kainate-induced excitotoxicity. May play a role in controlling neurotransmitter trafficking at the presynaptic terminal and in calcium-dependent exocytosis. Regulates cyclin E during neuronal apoptosis. May represent a tumor suppressor gene. SUBCELLULAR LOCATION: Cytoplasm. Co-localizes with STY11 in neutrites. Co-localizes with SNCAIP in brainstem Lewy bodies. TISSUE SPECIFICITY: Highly expressed in the brain including the substantia nigra. Expressed in heart, testis and skeletal muscle. Expression is down-regulated or absent in tumor biopsies, and absent in the brain of PARK2 patients. Overexpression protects dopamine neurons from kainate-mediated apoptosis.

Sequestosome 1 is an adapter protein which binds ubiquitin and may regulate the activation of NFKB1 by TNF-alpha, nerve growth factor and interleukin-1. It may regulate signaling cascades through ubiquitination and may also be involved in cell differentiation, apoptosis, immune response and regulation of K(+) channels. It is present as a homooligomer or heterooligomer and localises to the cytoplasm, late endosome and nucleus. In cardiac muscles it localises to the sarcomeric band. It accumulates in neurofibrillary tangles and in Lewy bodies of neurons from individuals with Alzheimer and Parkinson disease respectively. It is also enriched in Rosenthal fibers of pilocytic astrocytoma and in liver cells it accumulates in Mallory bodies associated with alcoholic hepatitis, Wilson disease, indian childhood cirrhosis and in hyaline bodies associated with hepatocellular carcinoma. Sequestosome 1 is ubiquitously expressed and to date, there are 2 named isoforms produced by alternative splicing. Defects in sequestosome 1 cause sporadic and familial Page disease of bone (PDB). This is a metabolic bone disease characterised by focal areas of increased and disorganised bone turn-over due to activated osteoclasts.

Caspases play several key roles in cellular growth and development, extracellular matrix remodeling, wound healing, homeostasis, and are implicated in a wide range of diseases from auto immune dysfunction to cancer metastases as well. Caspases are Cysteine ASpartate Proteases which form a family of metalloproteinases of which there are more than a dozen members. Caspases are all normally expressed in cells as inactive precursor zymogens that then get activated via proteolytic cleavage to form active enzyme complexes. Activation can occur by several means and programmed cell death, or apoptosis, is among the most studied, but there are several others since caspases are involved in so many critical and disease states. Among the 14 or so members, Caspase-6 is particularly interesting because it has been implicated in playing a role in some neurodegenerative diseases including Alzheimer's and Huntington's disease. Caspase-6 has been shown to cut amyloid precursor protein (APP), at position 720 leading to the toxic fragment Jcasp, which is one of the fragments found in amyloid plaques which are believed to be an indicator of the disease, and in Huntington's disease, the specific amino acid sequence (IVLD586G) is recognized by Caspase-6 on the Huntington protein (htt) in mice with Huntington's disease. The proteolytic cleavage of htt liberates toxic fragments containing the expanded polyglutamine tract that are neurotoxic and that stimulates additional proteolytic activity leading to apoptosis and neurodegeneration. Mutation of the Caspase-6 site in mice model with Alzheimer's and Huntington's disease provides protection from the neural dysfunction, suggesting a causal relationship between Caspase-6 cleavage and neurodegeneration. Biosensis is pleased to offer a rabbit polyclonal antibody to human Caspase 6 that reacts in paraffin embedded immunohistochemistry and western blotting for your continued research into Caspase 6 and its potential roles in both normal and pathological conditions.

Ubiquitin is a highly conserved 76 amino acid protein with an estimated molecular weight of 8.56 kDa which has a central role in regulated protein degradation. It is a protein modifier which can be covalently attached to target lysines either as a monomer or as a lysine-linked polymer. Several types of polymeric chains can be formed depending on the lysine used for the assembly. Attachment to proteins as a polymer leads to their degradation by the 26S proteosome; a complex, multicatalytic cytosolic and nuclear protease. Attachment to proteins as a monomer or as an alternatively linked polymer does not lead to proteasomal degradation and may be required for numerous functions, including maintenance of chromatic structure, regulation of gene expression, stress response, ribosome biogenesis and DNA repair. Ubiquitin is synthesized as a polyubiquitin precursor with exact head to tail repeats, the number of repeats of which differ between species and strains. In some species there is a final amino-acid after the last repeat, here in bovine a Cys. Some ubiquitin genes contain a single copy of ubiquitin fused to a ribosomal protein (either L40 or S27a).

LRRK2 is a member of the leucine-rich repeat kinase family. Its role is yet unknown but it may play a role in the phoshorylation of proteins central to parkinson diseases. LRRK2 contains an ankryin repeat region, a leucine-rich repeat (LRR) domain, a kinase domain, a DFG-like motif, a RAS domain, a GTPase domain, a mLK-like domain and a WD40 domain. LRRK2 is present in the cytoplasm but also associates with the mitochondrial outer membrane. Defects in LRRK2 are the cause of Parkinson disease 8 (PARK8). Parkinson disease is characterised by bradykinesia, resting tremor, muscular rigidity and postural instability, as well as by a clinically significant response to treatment with levodopa. The pathology involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain. PARK8 is an autosomal-dominant late-onset parkinsonism, characterized by onset from 50 to 65 years, with slow progression and relatively benign course.

FUNCTION: Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization. SUBCELLULAR LOCATION: Cytoplasm; cytosol. Cell membrane. Mostly found in the axons of neurons, in the cytosol and in association with plasma membrane components. ALTERNATIVE PRODUCTS: 8 named isoforms produced by alternative splicing. Additional isoforms seem to exist. Isoforms differ from each other by the presence or absence of up to 5 of the 15 exons. One of these optional exons contains the additional tau/MAP repeat. TISSUE SPECIFICITY: Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system. DEVELOPMENTAL STAGE: Four-repeat (type II) tau is expressed in an adult-specific manner and is not found in fetal brain, whereas three-repeat (type I) tau is found in both adult and fetal brain. DOMAIN: The tau/MAP repeat binds to tubulin. In Alzheimer disease, the neuronal cytoskeleton in the brain is progressively disrupted and replaced by tangles of paired helical filaments and straight filaments, mainly composed of hyperphosphorylated forms of Microtubule-associated protein Tau. Defects in Microtubule-associated protein Tau are a cause of frontotemporal dementia and parkinsonism linked to chromosome 17, as well as a number of other neurodegenerative diseases.

Alpha synuclein is an abundant 140 amino acid neuronal protein, expressed primarily at presynaptic terminals in the central nervous system. Alpha synuclein has been associated with several neurodegenerative diseases. A point mutation in the gene coding for the alpha-synuclein protein was the first discovery linking this protein to a rare familial form of Parkinson's disease (PD). Subsequently, other mutations in the alpha-synuclein gene have been identified in familial PD. The aggregated proteinaceous inclusions called Lewy bodies found in PD and cortical Lewy body dementia (LBD) were discovered to be predominantly alpha-synuclein. Aberrant aggregation of alpha-synuclein has been detected in an increasing number of neurodegenerative diseases, collectively known as synucleopathies. Alpha-synuclein exists physiologically in both soluble and membrane-bound states, in unstructured and alpha-helical conformations, respectively. The physiological function of alpha-synuclein appears to require its translocation between these subcellular compartments and interconversion between the 2 conformations. Abnormal processing of alpha-synuclein is predicted to lead to pathological changes in its binding properties and function.

In vitro, increases the susceptibility of neurofilament-H to calcium-dependent proteases. May also function in modulating the keratin network in skin. Activates the MAPK and Elk-1 signal transduction pathway. SUBUNIT: May be a centrosome-associated protein. SUBCELLULAR LOCATION: Cytoplasm; perinuclear region. Centrosome. Spindle. Associated with centrosomes in several interphase cells. In mitotic cells, localized to the poles of the spindle. TISSUE SPECIFICITY: Highly expressed in brain, particularly in the substantia nigra. Also expressed in the corpus callosum, heart, skeletal muscle, ovary, testis, colon and spleen. Weak expression in pancreas, kidney and lung. PTM: Phosphorylated. Phosphorylation by GRK5 appears to occur on residues distinct from the residue phosphorylated by other kinases. DISEASE: Brain iron accumulation type 1 (NBIA1, also called Hallervorden-Spatz syndrome), a rare neuroaxonal dystrophy, is histologically characterized by axonal spheroids, iron deposition, Lewy body (LB)-like intraneuronal inclusions, glial inclusions and neurofibrillary tangles. SNCG is found in spheroids but not in inclusions.

LRRK2 is a member of the leucine-rich repeat kinase family. It role is yet unknown but it may play a role in the phoshorylation of proteins central to parkinson diseases. LRRK2 contains an ankryin repeat region, a leucine-rich repeat (LRR) domain, a kinase domain, a DFG-like motif, a RAS domain, a GTPase domain, a mLK-like domain and a WD40 domain. LRRK2 is present in the cytoplasm but also associates with the mitochondrial outer membrane. Defects in LRRK2 are the cause of Parkinson disease 8 (PARK8). Parkinson disease is characterised by bradykinesia, resting tremor, muscular rigidity and postural instability, as well as by a clinically significant response to treatment with levodopa. The pathology involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain. PARK8 is an autosomal-dominant late-onset parkinsonism, characterized by onset from 50 to 65 years, with slow progression and relatively benign course.

Alpha synuclein is an abundant 140 amino acid neuronal protein, expressed primarily at presynaptic terminals in the central nervous system. Alpha synuclein has been associated with several neurodegenerative diseases. A point mutation in the gene coding for the alpha-synuclein protein was the first discovery linking this protein to a rare familial form of Parkinson's disease (PD). Subsequently, other mutations in the alpha-synuclein gene have been identified in familial PD. The aggregated proteinaceous inclusions called Lewy bodies found in PD and cortical Lewy body dementia (LBD) were discovered to be predominantly alpha-synuclein. Aberrant aggregation of alpha-synuclein has been detected in an increasing number of neurodegenerative diseases, collectively known as synucleopathies. Alpha-synuclein exists physiologically in both soluble and membrane-bound states, in unstructured and alpha-helical conformations, respectively. The physiological function of alpha-synuclein appears to require its translocation between these subcellular compartments and interconversion between the 2 conformations. Abnormal processing of alpha-synuclein is predicted to lead to pathological changes in its binding properties and function.

Beta-synuclein is a non-amyloid component of senile plaques found in Alzheimer disease. It could act as a regulator of SNCA aggregation. It protects neurons from staurosporine and 6 hydroxy dopamine -stimulated capspase activation in a p53-dependent manner. It localises to the cytoplasm and it is predominantly expressed in the brain where it is most concentrated in presynaptic nerve terminals. This protein is phosphorylated. This protein is also associated with the disease Brain iron accumulation type 1 (NBIA1).
