The co-repressor SMRT delays DNA damage-induced caspase activation by repressing pro-apoptotic genes and modulating the dynamics of checkpoint kinase 2 activation.
Checkpoint kinase 2 (Chk2) is a major regulator of DNA damage response and can induce alternative cellular responses: cell cycle arrest and DNA repair or programmed cell death.Here, we report the identification of a new role of Chk2 in transcriptional regulation that also contributes to Liquid Soap modulating the balance between survival and apopto
