SCFFbx4 was recently identified as the E3 ligase for cyclin D1. We now describe cell cycle-dependent phosphorylation and dimerization of Fbx4 that is regulated by GSK3β and defective in human cancer. We present data demonstrating that a pathway involving Ras-Akt-GSK3β controls the temporal phosphorylation and dimerization of the SCFFbx4 E3 ligase. Inhibition of Fbx4 activity results in accumulation of nuclear cyclin D1 and oncogenic transformation. The importance of this regulatory pathway for normal cell growth is emphasized by the prevalence of mutations in Fbx4 in human cancer that impair dimerization. Collectively, this data reveals that inactivation of the cyclin D1 E3 ligase will likely contribute to cyclin D1 overexpression in a significant fraction of human cancer.
