AB - <p>Increased transcriptional activity of β-catenin resulting from Wnt/Wingless-dependent or -independent signaling has been detected in many types of human cancer, but the underlying mechanism of Wnt-independent regulation is poorly understood. We have demonstrated that AKT, which is activated downstream from epidermal growth factor receptor signaling, phosphorylates β-catenin at Ser<sup>552</sup> <i>in vitro</i> and <i>in vivo</i>. AKT-mediated phosphorylation of β-catenin causes its disassociation from cell-cell contacts and accumulation in both the cytosol and the nucleus and enhances its interaction with 14-3-3ζ via a binding motif containing Ser<sup>552</sup>. Phosphorylation of β-catenin by AKT increases its transcriptional activity and promotes tumor cell invasion, indicating that AKT-dependent regulation of β-catenin plays a critical role in tumor invasion and development.</p>
