GSK3 Signaling

Glycogen synthase kinase 3 (GSK-3) in its active state complexes with APC and AXIN to suppress phosphorylation of β-catenin, which then gets degraded via the proteasome. GSK-3 becomes inactivated through the PI3K/AKT pathway when the cell receives signals like growth factors, cytokines, or insulin. WNT signaling can also inactivate GSK-3 through Dsh. Inactivation of GSK-3 leads to gene expression, cell survival, and cell proliferation.
