PARP1 (Poly(ADP-ribose) polymerase 1)

Summary of PARP1

The PARP1 gene codes for an enzyme (PARP1) that is activated whenever your body detects DNA damage in its cells. This enzyme then binds to the damaged DNA to “mark” it so that other natural repair processes can come in and start fixing the damage [R, R, R].

Although being able to repair your DNA is obviously a good thing, there’s a catch: PARP1 activation also triggers your body’s inflammatory response [R, R, R].

The trade-off between DNA repair and increased inflammation means that your levels of the PARP1 enzyme have to be held in a delicate balance to ensure optimal health. Too little of it, and your body and brain will be more susceptible to common forms of cellular DNA damage, such as oxidative stress – but too much of it, and you will be more likely to experience chronic inflammation.

Some SNPs in the PARP1 gene, such as rs7515023, have been associated with overall cognitive ability -- most likely because they determine how vulnerable your brain is to oxidative stress and inflammation ('T' = better, 'C' = worse) [R].

The Function of PARP1

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 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).
