Clinical PARP inhibitors do not abrogate PARP1 exchange at DNA damage sites in vivo

DNA breaks recruit and activate PARP1/2, which deposit poly-ADP-ribose (PAR) to recruit XRCC1-Ligase3 and other repair factors to promote DNA repair. Clinical PARP inhibitors (PARPi) extend the lifetime of damage-induced PARP1/2 foci, referred to as ‘trapping’. To understand the molecular nature of...
