PARG catalyzes the removal of poly(ADP-ribose) (PAR) from target proteins and executes critical functions in the DNA damage response. Here the authors provide structural and biological insight with small molecule PARG inhibitors and show that PARG inhibition sensitizes cells to ionizing radiation and kills cancer cells through replication fork defects.
