GSK3A
Glycogen synthase kinase-3 alpha is an enzyme that in humans is encoded by the GSK3A gene.
Glycogen synthase kinase 3-alpha is a multifunctional protein serine kinase, homologous to Drosophila 'shaggy' and implicated in the control of several regulatory proteins including glycogen synthase and various transcription factors. It also plays a role in the WNT and phosphoinositide 3-kinase signaling pathways.
