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 ...

Extracellular-Added ADP-Ribose Increases Intracellular Free Ca2+ Concentration Through Ca2+ Release From Stores, but Not Through TRPM2-Mediated Ca2+ Entry, in Rat β-Cell Line RIN-5F

Journal of Pharmacological Sciences, 2006
.: Intracellular ADP-ribose is an activator of TRPM2, which is a Ca2+-permeable channel and mediates H2O2-induced cell death, in the TRPM2-expressing rat β-cell line RIN-5F.

ADP-Ribose Activates the TRPM2 Channel from the Sea Anemone Nematostella vectensis Independently of the NUDT9H Domain. [PDF]

PLoS ONE, 2016
The human redox-sensitive Transient receptor potential melastatin type 2 (hTRPM2) channel contains the C-terminal Nudix hydrolase domain NUDT9H which most likely binds ADP-ribose.

Cyclic ADP-Ribose and Hydrogen Peroxide Synergize with ADP-Ribose in the Activation of TRPM2 Channels [PDF]

Molecular Cell, 2005
The melastatin-related transient receptor potential channel TRPM2 is a plasma membrane Ca2+-permeable cation channel that is activated by intracellular adenosine diphosphoribose (ADPR) binding to the channel's enzymatic Nudix domain. Channel activity is also seen with nicotinamide dinucleotide (NAD+) and hydrogen peroxide (H2O2), but their mechanisms ...

Poly(ADP-Ribose) Links the DNA Damage Response and Biomineralization

Cell Reports, 2019
Summary: Biomineralization of the extracellular matrix is an essential, regulated process. Inappropriate mineralization of bone and the vasculature has devastating effects on patient health, yet an integrated understanding of the chemical and cell ...

Poly(ADP-ribose) Polymerase Null Mouse Cells Synthesize ADP-ribose Polymers [PDF]

Journal of Biological Chemistry, 1998
Poly(ADP-ribose) polymerase (PARP) (EC 2.4.2.30), the only enzyme known to synthesize ADP-ribose polymers from NAD+, is activated in response to DNA strand breaks and functions in the maintenance of genomic integrity. Mice homozygous for a disrupted gene encoding PARP are viable but have severe sensitivity to gamma-radiation and alkylating agents.

Engineering Af1521 improves ADP-ribose binding and identification of ADP-ribosylated proteins

Nature Communications, 2020
ADP-ribose binding macro domains facilitate the enrichment and detection of cellular ADP-ribosylation. Here, the authors generate an engineered macro domain with increased ADP-ribose affinity, improving the identification of ADP-ribosylated proteins by ...

Synthesis of Dimeric ADP-Ribose and Its Structure with Human Poly(ADP-ribose) Glycohydrolase [PDF]

Journal of the American Chemical Society, 2015
Poly(ADP-ribosyl)ation is a common post-translational modification that mediates a wide variety of cellular processes including DNA damage repair, chromatin regulation, transcription, and apoptosis. The difficulty associated with accessing poly(ADP-ribose) (PAR) in a homogeneous form has been an impediment to understanding the interactions of PAR with ...

Inhibiting poly(ADP-ribosylation) improves axon regeneration

eLife, 2016
The ability of a neuron to regenerate its axon after injury depends in part on its intrinsic regenerative potential. Here, we identify novel intrinsic regulators of axon regeneration: poly(ADP-ribose) glycohodrolases (PARGs) and poly(ADP-ribose ...
