Abstract :Cell division relies on the activation of cyclins, which bind to cyclin-dependent kinases (CDKs) to induce cell cycle progression towards S phase and later to initiate mitosis. Since uncontrolled cyclin-dependent kinase activity is often the cause of human cancer, their function is tightly regulated by cell-cycle inhibitors such as the p21 and p27 Cip/Kip proteins. Following anti-mitogenic signals or DNA damage, p21 and p27 bind to cyclin-CDK complexes to inhibit their catalytic activity and induce cell-cycle arrest. Interestingly, recent discoveries suggest that p21 and p27 might have new activities that are unrelated to their function as CDK inhibitors. The identification of new targets of Cip/Kip proteins as well as evidence of Cip/Kip cytoplasmic relocalization have revealed unexpected functions of these proteins in the regulation of apoptosis. This article discusses recent insights into this possible additional functions of p21 and p27.
