Abstract

The maintenance of genome integrity is essential for the regulation of cell proliferation and differentiation. DNA must be accurately duplicated and segregated to daughter cells at cell division, a process that is primarily regulated by cyclin-dependent kinases (CDKs). During cell growth, however, it is inevitable that DNA breaks will occur due to endogenous and exogenous stresses. Interestingly, there is increasing evidence that the catalytic activities of CDKs play critical roles in the DNA damage response, especially in the case of damage repaired by the homologous recombination (HR) pathway. In this review, we outline current knowledge of CDK regulation and its roles both in the unperturbed cell cycle and in DNA damage responses, and discuss the physiological roles of CDKs in HR repair.
