The basic cleft of RPA70N binds multiple checkpoint proteins, including RAD9, to regulate ATR signaling.

abstract：:c-Myc promotes apoptosis by destabilizing mitochondrial integrity, leading to the release of proapoptotic effectors including holocytochrome c. Candidate mediators of c-Myc in this process are the proapoptotic members of the Bcl-2 family. We show here that fibroblasts lacking Bak remain susceptible to c-Myc-induced ap...
