The p16INK4a/p14ARF locus encodes two distinct cell cycle inhibitory proteins, p16INK4a and p14ARF (p19Arf in the mouse) by alternative first-exon usage and alternative reading frames (20). p16INK4a arrests cells in the G1 phase of the cell cycle by binding the cyclin-dependant kinases CDK4 and CDK6 and inhibiting their ability to phosphorylate and inactivate the retinoblastoma (RB1) family of tumor suppressor proteins (22). p14ARF acts through MDM2 to stabilize and activate the key checkpoint protein p53, which can arrest cells in both G1 and G2 or induce apoptosis (20). | |||||||||||||||
