DNA endonuclease CtIP is involved in both DNA double-strand break (DSB) repair and transcriptional repression/activation. The cyclin-dependent kinase inhibitor P21, which is induced at transcription level in response to a variety of stresses, controls G1/S transition. In this report, we found that CtIP bound to the P21 promoter, and this binding was enhanced in response to DNA damage. Concomitantly, ectopic expression of CtIP increased P21 promoter activity, and this increment was enhanced upon camptothecin treatment. Conversely, DNA damage failed to induce P21 gene expression in CtIP-deficient cells. Taken together, our data demonstrate that CtIP is required for DNA damage-induced P21 induction.
