Ligands: 78P, GOL Related: 3kcz Gene: ADPRT2, ADPRTL2, PARP2 (Homo sapiens) Activity: NAD(+) ADP-ribosyltransferase, with EC number 2.4.2.30 Resources: FirstGlance, OCA, RCSB, PDBsum Function [PARP2_HUMAN] Involved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks.

Publication Abstract from PubMed Poly-ADP-ribose polymerases (PARPs) catalyze transfer of ADP-ribose from NAD(+) to specific residues in their substrate proteins or to growing ADP-ribose chains. PARP activity is involved in processes such as chromatin remodeling, transcription control, and DNA repair. Inhibitors of PARP activity may be useful in cancer therapy. PARP2 is the family member that is most similar to PARP1, and the two can act together as heterodimers. We used X-ray crystallography to determine two structures of the catalytic domain of human PARP2: the complexes with PARP inhibitors 3-aminobenzamide and ABT-888. These results contribute to our understanding of structural features and compound properties that can be employed to develop selective inhibitors of human ADP-ribosyltransferases.
