Modulates negatively AKT-mediated GSK3B signaling.Induces CTNNB1 Ser-33 phosphorylation and degradation through the suppression of the inhibitory Ser-9 phosphorylation of GSK3B, which represses the function of the APC:CTNNB1:GSK3B complex and the interaction with CDH1/E-cadherin in adherent junctions.
