A ribose-functionalized NAD+ with unexpected high activity and selectivity for protein poly-ADP-ribosylation [PDF]

open access: yesNature Communications, 2019
The study of NAD+ dependent ADP-ribosylation can be challenging. Here the authors report on the development of NAD+ analogues, using chemo-enzymatic methods, which can be used as probes to label the substrate proteins of poly-ADP-ribose polymerase.

Inputs and outputs of poly(ADP-ribosyl)ation: Relevance to oxidative stress [PDF]

open access: yesRedox Biology, 2014
Oxidative stress can cause DNA breaks which induce activation of the DNA nick sensor enzyme poly(ADP-ribose) polymerase-1 (PARP-1), part of the 17 member PARP enzyme family.

Poly(ADP-ribose)polymerase inhibition decreases angiogenesis [PDF]

open access: yesBiochemical and Biophysical Research Communications, 2006
Inhibitors of poly(ADP-ribose)polymerase (PARP), a nuclear enzyme involved in regulating cell death and cellular responses to DNA repair, show considerable promise in the treatment of cancer both in monotherapy as well as in combination with ...

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 (

Protein poly(ADP-ribosyl)ation regulates arabidopsis immune gene expression and defense responses. [PDF]

open access: yesPLoS 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.

RNA Regulation by Poly(ADP-Ribose) Polymerases [PDF]

open access: yesMolecular Cell, 2015
Posttranscriptional regulation of RNA facilitates the fine-tuning of gene expression. It occurs through multiple pathways that include the nuclear processing of mRNA and its precursors, mRNA silencing, regulation of mRNA decay, and regulation of translation. Poly(ADP-ribose) polymerases (PARPs), enzymes that modify target proteins with ADP-ribose, play
