Background: GSK-3 alpha/beta

Glycogen Synthase Kinase 3beta (GSK-3beta) is a unique serine/threonine kinase that is inactivated by phosphorylation. In response to insulin binding, PKB/AKT phosphorylates GSK-3beta on serine 9, which prevents GSK-3beta from phosphorylating glycogen synthase. Unphosphorylated glycogen synthase is active and able to synthesize glycogen. GSK-3beta is also unique in that it requires a substrate that has been phosphorylated by a distinct kinase before it can phosphorylate the substrate. This phosphate priming mechanism explains why phosphorylation of serine 9 inactivates GSK-3beta. The phosphorylated serine binds to the GSK-3beta priming phosphate position and prevents binding of alternative substrates. In addition to insulin signaling, GSK-3beta participates in the Wnt signaling pathway, where it forms a complex with axin, beta-catenin and adenomatous polyposis coli (APC) protein. In the presence of Wnts, GSK-3beta is unable to phosphorylate beta-catenin, which leads to stabilization of beta-catenin. The Wnt pathway inactivates GSK-3beta via the proteins, Dishevelled and FRAT, which disrupt the interaction of GSK-3beta with axin, beta-catenin, and APC. Clinically, there is considerable interest in GSK-3beta inhibitors because they may mimic the effect of insulin or reduce the hyperphosphorylation of Tau that is observed in Alzheimer's Disease.
