Poly(ADP-ribose) polymerases (PARPs) modify target proteins post-translationally
with poly(ADP-ribose) (PAR) or mono(ADP-ribose) (MAR) using NAD(+) as substrate.
The best-studied PARPs generate PAR modifications and include PARP1 and the
tankyrase PARP5A, both of which are targets for cancer therapy with inhibitors in
either clinical trials or preclinical development. There are 15 additional PARPs,
most of which modify proteins with MAR, and their biology is less well
understood. Recent data identify potentially cancer-relevant functions for these
PARPs, which indicates that we need to understand more about these PARPs to
effectively target them.
