"WebCyclin A/cdk2 and Cyclin B/cdk1 maintains an inactive hyperphosphorylated Rb throughout S, G2 and M phase. pRb may perform other roles in addition to regulation of G1/S including the regulation of apoptosis. A decrease in functional pRb results in the activation of p53-induced apoptosis, which appears to be mediated via the release of E2F1. " - Cyclin b-cdk1
