Glycogen synthase kinase-3 (GSK-3) is a non-receptor protein serine/threonine kinase and a critical modulator of cell fate, neuronal plasticity, and tumorigenesis. GSK-3 consists of two isoforms, α (51 kDa) and β (47 kDa). Phosphorylation of the kinase activation loop on GSK-3α tyrosine 279 (tyrosine 216 for GSK-3β) by focal adhesion kinase (FAK) or proline-rich/Ca²⁺-activated tyrosine kinase (Pyk2) activates GSK-3α/β, inhibiting glycogen synthesis and thereby inducing apoptosis. GSK-3β also hyper-phosphorylates the microtubule binding protein Tau, leading to paired helical formation, a marker in the pathogenesis of Alzheimer's disease.

Rabbit anti-GSK3α[pY279]/β[pY216] polyclonal antibody has been purified from rabbit serum by epitope-specific affinity chromatography. The antibody has been negatively pre-adsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated GSK-3α/β. The final product is generated by affinity chromatography using a GSK-3α/β-derived peptide that is phosphorylated at tyrosine 279/216.
