Human poly(ADP-ribose) polymerase 3, catalytic fragment in complex with an inhibitor 3-aminobenzoic acid

Structural highlights

3fhb is a 1 chain structure with sequence from Human. This structure supersedes the now removed PDB entry 2pa9. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Gene:	PARP3, ADPRT3, ADPRTL3 (HUMAN)
Activity:	NAD(+) ADP-ribosyltransferase, with EC number 2.4.2.30
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[PARP3_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. May link the DNA damage surveillance network to the mitotic fidelity checkpoint. Negatively influences the G1/S cell cycle progression without interfering with centrosome duplication. Binds DNA. May be involved in the regulation of PRC2 and PRC3 complex-dependent gene silencing.^[1]

Publication Abstract from PubMed

Poly(ADP-ribose) polymerases (PARPs) activate DNA repair mechanisms upon stress- and cytotoxin-induced DNA damage, and inhibition of PARP activity is a lead in cancer drug therapy. We present a structural and functional analysis of the PARP domain of human PARP-3 in complex with several inhibitors. Of these, KU0058948 is the strongest inhibitor of PARP-3 activity. The presented crystal structures highlight key features for potent inhibitor binding and suggest routes for creating isoenzyme-specific PARP inhibitors.
