WebThe S-phase-specific cyclin-dependent kinase 2 was required for robust activation of ATR in response to diverse chemotherapeutic agents. The authors show that, in human and mouse, Mre11 controls these events through a direct interaction with CDK2 that is required for CtIP phosphorylation and BRCA1 interaction in normally dividing cells. 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

WebCyclin A resides in the nucleus during S phase where it is involved in the initiation and completion of DNA replication. As the cell passes from G 1 into S phase, cyclin A associates with CDK2, replacing cyclin E. Cyclin E is responsible for initiating the assembly of the pre-replication complex. This ...

WebAbstract. The cyclin-dependent kinase inhibitor p27 (Kip1) is known as a negative regulator of cell-cycle progression and as a tumour suppressor. Cdk2 is the main target of p27 (refs 2, 3) and therefore we hypothesized that loss of Cdk2 activity should modify the p27 (-/-) mouse phenotype.
