Poly(ADP-ribosyl)ation is catalyzed by a family of enzymes known as PARPs. We describe a method to characterize the human aspartic acid- and glutamic acid-ADP-ribosylated proteome. We identified 1,048 ADADP-ribosylation sites on 340 proteins involved in a wide array of nuclear functions; among these were many previously unknown PARP downstream targets whose ADP-ribosylation was sensitive to PARP inhibitor treatment. We also confirmed that iniparib had a negligible effect on PARP activity in intact cells.
