PARP8 (Poly(ADP-Ribose) Polymerase Family Member 8) is a Protein Coding gene. Among its related pathways are Metabolism and Mesodermal Commitment Pathway. Poly (ADP-ribose) polymerase (PARP) catalyzes the post-translational modification of proteins by the addition of multiple ADP-ribose moieties. PARP transfers ADP-ribose from nicotinamide dinucleotide (NAD) to Glu/Asp residues on the substrate protein.
