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.}, pages = {1--9}, title = {CDKインヒビターによるアポトーシス制御}, volume = {7}, year = {2011}, yomi = {カジハラ, リュウタロウ and フクシゲ, ショウタ and タナベ, カノ and イヌイ, セイジ} }
