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. Plays a role in the regulation of cell cycle and cell adhesion. Has an inhibitory role on AR-signaling pathway through the induction of receptor proteosomal degradation. Interacts with the complex composed, at least, of APC, CTNNB1 and GSK3B; the interaction takes place with the inactive form of GSK3B (phosphorylated at 'Ser-9'). Belongs to the JUPITER family.
