Poly(ADP-ribose) polymerase 2 (PARP2) is activated by 5′-phosphorylated DNA breaks but the molecular mechanism is not fully understood. Here, the authors report a crystal structure of PARP2 bound to an activating DNA fragment, providing insights into the structural changes that lead to PARP2 activation.
