AKT1 E17K gain-of-function mutant preserves the ability to phosphorylate GSK3 (Malanga et al. 2008). AKT-mediated phosphorylation inactivates GSK3 and enables WNT-independent stabilization of beta-catenin (CTNNB1) (Haq et al. 2003). AKT-mediated inactivation of GSK3 also triggers changes in glucose metabolism (Ueki et al. 1997).
