Cyclin-dependent kinases in DNA damage response

The cyclin-dependent kinase (CDK) family plays a critical role in a variety of signaling pathways that regulate transcription and cell-cycle progression. Recently, the role of CDKs in DNA damage response (DDR) has emerged. CDKs affect both damage signaling and DNA repair, contributing to the fidelity of the cell division process as well as the maintenance of genomic integrity following DNA damage. This is due to the modulatory role of CDKs on double-strand break repair (DSBR) components, including their influence on enzymes involved in homologous recombination (HR) and non-homologous end-joining (NHEJ). In this review, the impact of CDKs on DDR and DNA repair is discussed.
