NH2OH was used to remove PAR from the PARylated proteins. This treatment left on the PARylated residues a hydroxamic acid derivative, which has a signature mass increase of +15.0109 Da and could be distinguished by mass spectrometry.

Chromatin relaxation is a prerequisite step that allows the DNA repair machinery to access double-strand breaks (DSBs), and local histones around the DNA breaks suffer from prompt acetylation changes. However, an intriguing question remains as to where the large demands of acetyl-CoA is precisely pr...

Covalent PARylation of DNA base excision repair proteins regulates DNA demethylation
PARP1-mediated PARylation activity is essential for oligodendroglial differentiation and CNS myelination
XAV-939 is an anti-oncogenic small molecule that potently inhibits tankyrase1/2 (TNKS1/2), thereby blocking protein poly ADP-ribosylation (PARylation) of pleiotropic protein targets. In the present study, XAV-939 was used to explore its potential for improving human-derived liver models in vitro. Ep...

Poly(ADP-ribose) polymerases (PARP1 and PARP2) contribute to DNA base excision repair (BER) and DNA demethylation and has been implicated in epigenetic programming in early mammalian development. Recently, proteomic analyses identified BER proteins to be covalently poly-ADP-ribosylated by PARPs. The...
