摘要: The cellular response to ionizing radiation (IR) includes the induction of apoptosis. p300/CBP proteins possess histone acetyltransferase activity and function as transcriptional coactivators p53. We have prepared cells deficient in p300 or CBP define roles these DNA damage. present results demonstrate that p300, but not CBP, contributes IR sensitivity cells. also IR-induced apoptosis is impaired p300-, CBP-, These findings indicate functions apoptotic
