The 53BP1-dependent end-joining pathway plays a critical role in double-strand break (DSB) repair. However, the regulators of 53BP1 in chromatin remain incompletely characterized. In this study, we identified HDGFRP3 (hepatoma-derived growth factor related protein 3) as a 53BP1-interacting protein. The

The human single-stranded DNA-binding protein, replication protein A (RPA), is regulated by the N-terminal phosphorylation of its 32-kDa subunit, RPA2. RPA2 is hyperphosphorylated in response to various DNA-damaging agents and also phosphorylated in a cell-cycle-dependent manner during S- and M-phase
