PPM1D suppresses p53-dependent transactivation and cell death by inhibiting the Integrated Stress Response
Abstract
The authors describe a functional crosstalk between the p53 network and the integrated stress response through the p53 repressor PPM1D. Inhibition of PPM1D potentiates p53-dependent transactivation and apoptosis via induction of the HRI-eIF2α-ATF4 pathway.
