Cas9 is mostly orthogonal to human systems of DNA break sensing and repair.

open access: yesPLoS ONE, 2023
CRISPR/Cas9 system is а powerful gene editing tool based on the RNA-guided cleavage of target DNA. The Cas9 activity can be modulated by proteins involved in DNA damage signalling and repair due to their interaction with double- and single-strand breaks (

Emerging roles of eraser enzymes in the dynamic control of protein ADP-ribosylation

open access: yesNature Communications, 2019
ADP-ribose erasing enzymes are increasingly recognized as critical regulators of protein ADP-ribosylation dynamics in living systems. Here, the authors review recent advances in the discovery and characterization of ADP-ribose erasers and discuss their ...

Inhibition of poly (ADP-ribose) synthetase attenuates neutrophil recruitment and exerts anti-inflammatory effects [PDF]

open access: yes, 1997
A cytotoxic cycle triggered by DNA single-strand breakage and poly (ADP-ribose) synthetase activation has been shown to contribute to the cellular injury during various forms of oxidant stress in vitro.

ADP-ribosylation: from molecular mechanisms to human disease [PDF]

open access: yesGenetics and Molecular Biology
Post-translational modification of proteins by ADP-ribosylation, catalysed by poly (ADP-ribose) polymerases (PARPs) using NAD+ as a substrate, plays central roles in DNA damage signalling and repair, modulates a range of cellular signalling cascades and ...

Methods for Purification of Proteins Associated with Cellular Poly(ADP-Ribose) and PARP-Specific Poly(ADP-Ribose)

open access: yes, 2011
available in PMC 2012 November 09Poly(ADP-ribose) (pADPr) is a posttranslational modification that regulates protein function through two major mechanisms: covalent modification of acceptor proteins and noncovalent binding of proteins to pADPr.

ADP-ribose polymer - a novel and general biomarker of human cancers of head & neck, breast, and cervix

open access: yesMolecular Cancer, 2010
Background Poly-ADP-ribosylation, a reversible post-translational modification of primarily chromosomal proteins, is involved in various cellular and molecular processes including carcinogenesis.

Crystallographic and biochemical analysis of the mouse poly(ADP-ribose) glycohydrolase. [PDF]

open access: yesPLoS ONE, 2014
Protein poly(ADP-ribosyl)ation (PARylation) regulates a number of important cellular processes. Poly(ADP-ribose) glycohydrolase (PARG) is the primary enzyme responsible for hydrolyzing the poly(ADP-ribose) (PAR) polymer in vivo.

Recruitment of ubiquitin-activating enzyme UBA1 to DNA by poly(ADP-ribose) promotes ATR signalling

open access: yesLife Science Alliance, 2018
Human but not yeast UBA1 binds poly(ADP-ribose) polymers via a solvent-exposed and positively charged patch. Poly(ADP-ribose) polymerase 1–dependent recruitment of UBA1 to DNA ensures ataxia-telangiectasia and RAD3-related activation.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The Ups and Downs of Tannins as Inhibitors of Poly(ADP-Ribose)glycohydrolase

open access: yesMolecules, 2011
DNA damage to cells activates nuclear poly(ADP-ribose)polymerases (PARPs) and the poly(ADP-ribose) (PAR) synthesized is rapidly cleaved into ADP-ribose (ADPR) by PAR glycohydrolase (PARG) action.
