Modulates negatively AKT-mediated GSK3B signaling (PubMed:21323578, PubMed:22155408). 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 (PubMed:25169422). Plays a role in the regulation of cell cycle and cell adhesion (PubMed:25169422, PubMed:25450365). Has an inhibitory role on AR-signaling pathway through the induction of receptor proteosomal degradation (PubMed:22155408). 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'). Expressed in testis, skeletal muscle, thymus, prostate, colon, peripheral blood cells, brain and placenta. Induced by EGF growth factor at mRNA and protein levels (PubMed:21323578). Induced by androgens (PubMed:22155408). Negatively regulated by the microRNA miR-132 (PubMed:25450365). Belongs to the JUPITER family.
