Technical Data
Tau (Microtubule-associated Protein Tau, Neurofibrillary Tangle Protein, Paired Helical Filament-tau, PHF-tau, MAPT, MAPTL, MTBT1)
Tau is a collection of microtubule-associated proteins that is involved in microtubule assembly and stabilization. In adult human brain, 6 isoforms, ranging between 352 and 441aa in length, are produced as a result of alternative RNA splicing. The expression of tau isoforms is developmentally regulated, as only the smallest tau polypeptide is expressed in the fetal brain. Hyperphosphorylated Tau is the major component of the paired helical filament of Alzheimer's disease. Anti-phosphor-Tau antibodies are used to identify specific aa that are phosphorylated in Tau from normal brains and Alzheimer's disease brains. The Tau proteins, especially in developing brains and in Alzheimer brains, can be found to be phosphorylated in vivo at many different sites.
