Tau (Microtubule-associated Protein Tau, Neurofibrillary Tangle Protein, Paired Helical Filament-tau, PHF-tau, MAPT, MAPTL, MTBT1)
Description:
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 fetal brain. Hyperphosphorylated Tau is the major component of the paired helical filament of Alzheimer’s Disease. Phosphorylation-dependent anti-Tau antibodies are used to identify specific aa that are phosphorylated in tau from normal brain and Alzheiner’s disease brain. The Tau proteins, esp. in developing brain and in Alzheimer brains, were found to phosphorylate in vivo at many different sites.
