Frontiers in Molecular Biosciences, 2020 Poly(ADP-ribose) polymerases (PARPs) are a family of enzymes that catalyze the addition of poly(ADP-ribose) (PAR) subunits onto themselves and other acceptor proteins.

The Viral Macrodomain Counters Host Antiviral ADP-Ribosylation
Viruses, 2020 Macrodomains, enzymes that remove ADP-ribose from proteins, are encoded by several families of RNA viruses and have recently been shown to counter innate immune responses to virus infection.

F1000Research, 2016 After a DNA damage signal multiple polymers of ADP ribose attached to poly(ADP) ribose (PAR) polymerases (PARPs) are broken down by the enzyme poly(ADP) ribose glycohydrolase (PARG).

Cell Death and Disease, 2023 Parthanatos is one of the major pathways of programmed cell death in ischemic stroke characterized by DNA damage, poly (ADP-ribose) polymerases (PARP) activation, and poly (ADP-ribose) (PAR) formation.

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

PARP1 exhibits enhanced association and catalytic efficiency with γH2A.X-nucleosome
Nature Communications, 2019 The poly(ADP-ribose) polymerases play a key role in maintaining genomic integrity by detecting DNA damage and mediating repair. Here the authors characterize the kinetics of PARP1 binding to a variety of nucleosomes harbouring DNA double-strand breaks.

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

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Poly(ADP‐ribose) polymerase is a zinc metalloenzyme [PDF]
European Journal of Biochemistry, 1984 Purified poly(ADP‐ribose) polymerase was inhibited by 1,10‐phenanthroline at pH <8. This inhibition and the inhibition by other chelating agents suggested that this enzyme was a metalloprotein. Atomic absorption spectroscopy showed the presence of one atom of zinc per protein molecule.

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
