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.

Журнал органічної та фармацевтичної хімії, 2023 Poly(ADP-ribose) polymerases (PARPs) are key enzymes in the DNA repair pathway. Inhibitors of these enzymes belong to a new type of anticancer drugs that selectively kill cancer cells by targeting the homologous recombination genetic defects.

Novel modulators of poly(ADP-ribose) polymerase [PDF]
Trends in Pharmacological Sciences, 2006 The nuclear enzyme poly(ADP-ribose) polymerase (PARP)-1 has an important role in regulating cell death and cellular responses to DNA repair. Pharmacological inhibitors of PARP have entered clinical testing as cytoprotective agents in cardiovascular diseases and as adjunct antitumor therapeutics.

ADP-ribosylation: from molecular mechanisms to human disease [PDF]
Genetics and Molecular BiologyPost-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 ...

Poly(ADP‐Ribose) Polymerase in Plant Nuclei [PDF]
European Journal of Biochemistry, 1994 We show that poly(ADP‐ribose) polymerase is present in maize, pea and wheat nuclei. We have identified the enzyme product as poly(ADP‐ribose) by purification and electrophoresis on a DNA sequencing gel. This reveals a polymer ladder consisting of up to 45 residues. The polymer product from maize, after digestion with snake venom phosphodiesterase, gave

Structures of the human poly (ADP-ribose) glycohydrolase catalytic domain confirm catalytic mechanism and explain inhibition by ADP-HPD derivatives. [PDF]
PLoS ONE, 2012 Poly(ADP-ribose) glycohydrolase (PARG) is the only enzyme known to catalyse hydrolysis of the O-glycosidic linkages of ADP-ribose polymers, thereby reversing the effects of poly(ADP-ribose) polymerases.

PARP12 is required for mitochondrial function maintenance in thermogenic adipocytes
Adipocyte, 2022 PARP12 is a member of poly-ADP-ribosyl polymerase (PARPs), which has been characterized for its antiviral function. Yet its physiological implication in adipocytes remains unknown.
