| Background Information | Microtubule-associated protein tau (UniProt P29172; also known as Neurofibrillary tangle protein, Paired helical filament-tau, PHF-tau) is encoded by the MAPT (also known as TAU) gene (Gene ID 281296) in bovine species. Extracellular plaque deposits composed of amyloid-β and intracellular neurofibrillary tangles (NFTs) composed of truncated and hyperphosphorylated tau are two neuropathological hallmarks of Alzheimers disease (AD). Tau pathology (tauopathy) can cause toxicity when the brain is devoid of amyloid plaques, and tangle pathology correlates better with clinical dementia than amyloid pathology. Abnormal processing of tau by hyperphosphorylation and proteolytic truncation contribute to the toxicity of tau. Tau is known to be cleaved by various proteases, including caspases, calpains, cathepsins, thrombin, and puromycin-sensitive aminopeptidase, as well as the lysosomal cysteine proteinase asparagine endopeptidase (AEP). MAPK, GSK-3, and Cdk-5 are three known kinases that target various tau phosphorylation sites. Tau also undergoes other types of posttranslational modifications, including glycosylation, ubiquitination, glycation, polyamination, nitration, and lysine methylation, which are believed to be important for its non-pathological functions, including polymerization and stabilization of microtubules. |

| Specificity | Clone PC1C6 was originally designated as clone Tau-1. Clone PC1C6 (Tau-1) was initially thought to specifically target a form of tau present in axons by immunohistochemical staining of rat brain tissue (Binder, L.I. et al. (1985). J. Cell Biol. 101(4):1371-1378), later studies revealed that its immunoreactivity and therefore tissue staining pattern depends on the state of tau phosphorylation. Specifically, clone Tau-1 displayed diminished immunoreactivity toward Tau when phosphorylated in its epitope region. Sample dephosphorylation by alkaline phosphatase treatment enhanced the immunoreactivity of this clone in Western blotting and immunohistochemistry applications (Papasozomenos, S.C., and Binder, L.I. (1987) Cell Motil. Cytoskeleton. 8(3):210-216; Szendrei, G.I., et al. (1993). J. Neurosci. Res. 34(2):243-249); Billingsley, M.L., and Kincaid, R.L. (1997). Biochem.
