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, alpha (51kD) and beta (47kD).
Phosphorylation of the kinase activation loop on GSK-3alpha tyrosine 279 (tyrosine 216 for GSK-3beta) by focal adhesion kinase (FAK) or proline-rich/Ca2+-activated tyrosine kinase (Pyk2) activates GSK-3a,b, inhibiting glycogen synthesis and thereby inducing apoptosis.
GSK-3beta also hyperphosphorylates the microtubule- binding protein Tau, leading to paired helical formation, a marker in the pathogenesis of Alzheimer’s Disease.
