PARP3
PARP3 (Protein mono-ADP-ribosyltransferase PARP3) is an enzyme. The public catalogues list it as a drug target and a DNA repair gene, and an approved or late-stage drug is recorded against it. Tied to Ovarian cancer and Prostate cancer. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Mono-ADP-ribosyltransferase that mediates mono-ADP-ribosylation of target proteins and plays a key role in the response to DNA damage. Mediates mono-ADP-ribosylation of glutamate, aspartate or lysine residues on target proteins. In contrast to PARP1 and PARP2, it is not able to mediate poly-ADP-ribosylation. Involved in DNA repair by mediating mono-ADP-ribosylation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism, such as histone H2B, XRCC5 and XRCC6. ADP-ribosylation follows DNA damage and appears as an obligatory step in a detection/signalling pathway leading to the reparation of DNA strand breaks. Involved in single-strand break repair by catalysing mono-ADP-ribosylation of histone H2B on 'Glu-2' (H2BE2ADPr) of nucleosomes containing nicked DNA. Location: Nucleus; Chromosome; Cytoplasm, cytoskeleton, microtubule organizing center, centrosome; Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole (UniProt). Locus 3p21.2 (HGNC).
