PARP (Poly ADP‐ribose Polymerase) Family in Health and Disease [PDF]
MedCommThe poly(ADP‐ribose) polymerase (PARP) family consists of 17 members of nicotinamide adenine dinucleotide (NAD⁺)‐dependent enzymes that regulate key biological processes by catalyzing adenosine diphosphate (ADP)‐ribosylation, either poly(ADP‐ribosyl ...

PARG Mutation Uncovers Critical Structural Determinant for Poly(ADP-Ribose) Hydrolysis and Chromatin Regulation in Embryonic Stem Cells [PDF]
CellsPoly(ADP-ribosyl)ation is a crucial posttranslational modification that governs gene expression, chromatin remodeling, and cellular homeostasis. This dynamic process is mediated by the opposing activities of poly(ADP-ribose) polymerases (PARPs), which ...

Selective monitoring of the protein-free ADP-ribose released by ADP-ribosylation reversal enzymes.
PLoS ONE, 2021 ADP-ribosylation is a key post-translational modification that regulates a wide variety of cellular stress responses. The ADP-ribosylation cycle is maintained by writers and erasers.

Protein poly(ADP-ribosyl)ation regulates arabidopsis immune gene expression and defense responses. [PDF]
PLoS Genetics, 2015 Perception of microbe-associated molecular patterns (MAMPs) elicits transcriptional reprogramming in hosts and activates defense to pathogen attacks. The molecular mechanisms underlying plant pattern-triggered immunity remain elusive.

Chromatin composition is changed by poly(ADP-ribosyl)ation during chromatin immunoprecipitation. [PDF]
PLoS ONE, 2012 Chromatin-immunoprecipitation (ChIP) employs generally a mild formaldehyde cross-linking step, which is followed by isolation of specific protein-DNA complexes and subsequent PCR testing, to analyze DNA-protein interactions.

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

Chromosomal instability syndromes are sensitive to poly ADP-ribose polymerase inhibitors
Haematologica, 2008 Poly ADP-ribose polymerase inhibitors have been shown to target cells with homologous recombination DNA repair defects. We report that poly ADP-ribose polymerase inhibitors induces apoptosis in cells deficient in other key DNA repair components ...

The XRCC1 phosphate-binding pocket binds poly (ADP-ribose) and is required for XRCC1 function [PDF]
, 2015 Poly (ADP-ribose) is synthesized at DNA single-strand breaks and can promote the recruitment of the scaffold protein, XRCC1. However, the mechanism and importance of this process has been challenged.
