Cdk2 s phase

WebA-CDK2 is implicated in the control of DNA replication because ectopic expres sion of cyclin A promotes S phase and downregulation of cyclin A impedes S phase (reviewed in ref. 5). Cyclin A/E-CDK2 complexes are also implicated in preventing rereplication. OF AMBITION—COMMITMENT TO S PHASE BY CDK PHOSPHORYLATION OF pRB Webvents cells with damaged DNA from entering S-phase. Pre-viously, we have shown that downregulation of cyclin-dependent kinase 2 (CDK2) in hESC causes G1 arrest, loss of pluripotency, upregulation of cell cycle inhibitors p21 and p27 and differentiation toward extraembryonic line-ages. In this study, we investigate in detail the role of CDK2
