Serine-linked PARP1 auto-modification controls PARP inhibitor response
PARP inhibitors function by trapping PARP1 protein on DNA breaks, which has cytotoxic consequences to cancer cells. Here the authors identify three serine residues within PARP1 as key sites whose efficient HPF1-dependent modification counters PARP1 trapping and contributes to inhibitor tolerance.
