p21WAF1 mutations and human malignancies.

Abstract excerpt

During the past few years, several categories of cyclin-dependent kinase inhibitors (CDKIs), which negatively regulate cyclin/cyclin-dependent kinase (CDK) activities, were cloned. The p21WAF1, also known as CIP1 or SDI1, was the first reported CDKI: it's expression is induced by wild-type p53. The p21WAF1 is a potent inhibitor of most cyclin/CDK complexes and also inhibits the ability of the proliferating cell...
