Anti-PARP PARP1 Antibody

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .

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 (PubMed:17177976, PubMed:18172500, PubMed:19344625, PubMed:19661379, PubMed:23230272) . Mediates the poly (ADP-ribosyl) ation of APLF and CHFR (PubMed:17396150) . 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 (PubMed:17177976) . Required for PARP9 and DTX3L recruitment to DNA damage sites (PubMed:23230272) . PARP1-dependent PARP9-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites (PubMed:23230272) . Mediates serine ADP-ribosylation of target proteins following interaction with HPF1; HPF1 conferring serine specificity (PubMed:28190768) . Mediates the poly (ADP-ribosyl) ation of histones in a HPF1-dependent manner (PubMed:27067600) . Involved in the synthesis of ATP in the nucleus, together with NMNAT1, PARG and NUDT5 (PubMed:27257257) . Nuclear ATP generation is required for extensive chromatin remodeling events that are energy- consuming (PubMed:27257257) .
