Histone parylation
Webba reaction known as PARylation. Primary targets of PARP1/ PARP2 activities are histones, the protein components of nucleo-somes that structure the genome in all eukaryotes to form chroma-tin. PARylation of histones is mediated by histone PARylation factor 1 (HPF1), which contributes to a shared active site with … Webb18 aug. 2014 · Here, we show that PARylation confers the ability to bind histones and to assemble nucleosomes upon PARP-1, and also affects its interaction with chromatin. The rapid turnover of PAR groups provides a mechanism for switching PARP-1 function from nucleosome binder to nucleosome assembler.

ADP-ribosylation is a PTM of a wide variety of target proteins, including histones [20, 23, 26].However, since histone tails are subject to many types of PTMs, crosstalk between different modifications likely exists.
WebbHistone deacetylase inhibition (HDACi) and trichostatin A (TSA) may impair the NHEJ pathway by promoting PARP1 acetylation in leukemia cells. MORC2-mediated NAT10 acetylates PARP1 at K949 to promote its own stability and PARylation, which further enhances NHEJ repair in colon, breast, prostate, and pancreatic cancers. Webb12 maj 2024 · Poly-ADP-ribosylation (PARylation) is central to the important functions of PARP enzymes in the DNA damage response and nucleosome remodelling. Activation of PARP happens through DNA binding via zinc fingers and/or the WGR domain.
