Identification of PARP14 inhibitors using novel methods for detecting auto-ribosylation

Poly(ADP-ribose) polymerases (PARPs) use nicotinamide adenine dinucleotide (NAD+) as a co-substrate to transfer ADP-ribose when it releases nicotinamide as the metabolized product. Enzymes of the PARP family play key roles in detecting and repairing DNA, modifying chromatin, regulating transcription, controlling energy metabolism, and inducing cell death. PARP14, the original member of the PARP family, has been reported to be associated with the...
