Phospho-Tau (Thr181) Monoclonal Antibody (AT270), Invitrogen™

Mouse Monoclonal Antibody

Brand:  Invitrogen MN1050

Product Code. 11808711

Description

MN1050 recognizes PHF-Tau, tangles and neurofilaments. Cross reacts weakly with normal Tau. Does not cross react with recombinant unphosphorylated Tau. The epitope of this antibody is the phosphorylated Thr181 residue (numbering according to human Tau40). MN1050 detects PHF-tau (Thr181) which has a predicted molecular weight of approximately 79 kDa. Purity is >95% as determined by SDS-PAGE.

Tau is a neuronal microtubule-associated protein found predominantly on axons. The function of Tau is to promote tubulin polymerization and stabilize microtubules. 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/MAPT localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton while the longer isoforms may preferentially play a role in its stabilization. In its hyper-phosphorylated form, Tau is the major component of paired helical filaments (PHF), the building block of neurofibrillary lesions in Alzheimer's diseases (AD) brain. Hyper-phosphorylation impairs the microtubule binding function of Tau, resulting in the destabilization of microtubules in AD brains, μgtimately leading to the degeneration of the affected neurons. Numerous serine/threonine kinases phosphorylate Tau, including GSK-3beta, protein kinase A (PKA), cyclin-dependent kinase 5 (cdk5) and casein kinase II. Hyper-phosphorylated Tau is found in neurofibrillary lesions in a range and other central nervous system disorders such as Pick's disease, frontotemporal dementia, cortico-basal degeneration and progressive supranuclear palsy.
