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.

WebCDK2 is a member of the Cyclin‐Dependent Kinase family that is ubiquitously expressed. CDK2 is a catalytic subunit of the cyclin‐dependent protein kinase complex, whose activity is restricted to the G1‐S phase, and essential for cell cycle G1/S phase transition.

CDK levels remain relatively constant throughout the cell cycle and most regulation is post-translational. Most knowledge of CDK structure and function is based on CDKs of S. pombe (Cdc2), S. cerevisiae (CDC28), and vertebrates (CDC2 and CDK2).
