|Function||Constitutively active protein kinase that acts as a negative regulator in the hormonal control of glucose homeostasis, Wnt signaling and regulation of transcription factors and microtubules, by phosphorylating and inactivating glycogen synthase (GYS1 or GYS2), CTNNB1/beta-catenin, APC and AXIN1. Requires primed phosphorylation of the majority of its substrates. Contributes to insulin regulation of glycogen synthesis by phosphorylating and inhibiting GYS1 activity and hence glycogen synthesis. Regulates glycogen metabolism in liver, but not in muscle. May also mediate the development of insulin resistance by regulating activation of transcription factors. In Wnt signaling, regulates the level and transcriptional activity of nuclear CTNNB1/beta-catenin. Facilitates amyloid precursor protein (APP) processing and the generation of APP-derived amyloid plaques found in Alzheimer disease. May be involved in the regulation of replication in pancreatic beta-cells. Is necessary for the establishment of neuronal polarity and axon outgrowth. Through phosphorylation of the anti-apoptotic protein MCL1, may control cell apoptosis in response to growth factors deprivation.|

Glycogen synthase kinase 3-alpha is a multifunctional protein serine kinase. GSK-3 phosphorylates and inactivates glycogen synthase. It has also been implicated in the regulation of cell fate in Dictyostelium and is a component of the Wnt signaling pathway required for Drosophila, Xenopus, and mammalian development. GSK-3 has been shown to regulate Cyclin D1 proteolysis and subcellular localization. GSK-3alpha (GSK-3α) regulates the production of amyloid-beta peptides, a major component of the plaques that accumulate with progression of Alzheimer's disease, by phosphorylating Tau proteins. This presents the possibility that defects in GSK-3 signaling can contribute to the onset of Alzheimer’s disease. GSK-3α can be phosphorylated by Akt at Ser21. This phosphorylation of GSK-3α negatively regulates its kinase activity.
