General description

Tau is a neuronal microtubule-associated protein found predominantly on axons and functions to promote tubulin polymerization and stabilize microtubules. Tau, in its hyperphosphorylated form, is the major component of paired helical filaments (PHF), the building block of neurofibrillary lesions in Alzheimer′s disease (AD) brain. Hyperphosphorylated Tau is also found in neurofibrillary lesions in a range of other central nervous system disorders. Hyperphosphorylation impairs the microtubule binding function of Tau, resulting in the destabilization of microtubules in AD brains, ultimately leading to the degeneration of the affected neurons. Numerous serine/threonine kinases, including GSK-3beta, protein kinase A (PKA), cyclin-dependent kinase 5 (cdk5) and casein kinase II (CK2), phosphorylate Tau. Serines 199 and 202 are phosphorylated by GSK-3beta and have been linked to hereditary frontotemporal dementia. Serine 202 phosphorylation by cdk5, stimulated by the presence of microtubules, has been linked to hereditary neurodegenerative disease.

Specificity

Tau phosphoSerine 199/202. The antibody recognizes Tau pSerine 199/202 in samples of recombinant human Tau treated with GSK-3beta for 45 minutes. The reactivity of the antibody is blocked with the pSerine 199/202 peptide but not the non-phosphopeptide, tau phosphopeptide corresponding to pSerine 199, tau phosphopeptide corresponding to pSerine 202 or a generic phosphoSerine-containing peptide.

Immunogen

Synthetic peptide of amino acids surrounding the phosphoSerine 199 and 202 sites of human Tau.

Application

Detect Tau phospho Serine 199/202 using this Anti-Tau phospho Serine 199/202 Antibody validated for use in WB.
