| + | [https://www.uniprot.org/uniprot/PARP1_HUMAN PARP1_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. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150. With EEF1A1 and TXK, forms a complex that acts as a T-helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFN-gamma to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production.<ref>PMID:17177976</ref> <ref>PMID:18172500</ref> <ref>PMID:19344625</ref> <ref>PMID:19661379</ref> | ||

The crystal structure of human recombinant poly(ADP-ribose) polymerase (PARP) complexed with a potent inhibitor, FR257517, was solved at 3.0 A resolution. The fluorophenyl part of the inhibitor induces an amazing conformational change in the active site of PARP by motion of the side chain of the amino acid, Arg878, which forms the bottom of the active site. Consequently, a corn-shaped hydrophobic subsite, which consists of the side chains of Leu769, Ile879, Pro881, and the methylene chain of Arg878, newly emerges from the well-known active site. | The crystal structure of human recombinant poly(ADP-ribose) polymerase (PARP) complexed with a potent inhibitor, FR257517, was solved at 3.0 A resolution.
