Structural modeling of NAD+ binding modes to PARP-1
The nuclear protein poly (ADP-ribose) polymerase-1 (PARP-1) plays an important role in the signaling and repair of DNA. PARP-1 catalyses covalent binding of poly (ADP-ribose) polymers with itself as well as with other acceptor proteins using NAD+ as a ...

Recruitment of ubiquitin-activating enzyme UBA1 to DNA by poly(ADP-ribose) promotes ATR signalling
Human but not yeast UBA1 binds poly(ADP-ribose) polymers via a solvent-exposed and positively charged patch. Poly(ADP-ribose) polymerase 1–dependent recruitment of UBA1 to DNA ensures ataxia-telangiectasia and RAD3-related activation.

Structure, function and inhibition of poly(ADP-ribose)polymerase, member 14 (PARP14) [PDF]
Poly(ADP-ribose)polymerase, member 14 (PARP14, alternatively named ARTD8, BAL2, and COAST6) is an intracellular mono(ADP-ribosyl) transferase. PARP14 transfers a negatively charged ADP-ribose unit from a donor NAD+ molecule onto a target protein, post ...

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

The XRCC1 phosphate-binding pocket binds poly (ADP-ribose) and is required for XRCC1 function [PDF]
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.

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

Mcl-1 suppresses abasic site repair following bile acid–induced hepatic cellular DNA damage
In cholestasis, increases in bile acid levels result in the generation of reactive oxygen species and the induction of DNA damage and mutation. It is believed that bile acid accumulation is associated with liver tumorigenesis. However, the mechanism that

Nitrosative Stress as a Modulator of Inflammatory Change in a Model of Takotsubo Syndrome
Summary: Previous studies have shown that patients with Takotsubo syndrome (TS) have supranormal nitric oxide signaling, and post-mortem studies of TS heart samples revealed nitrosative stress.

Selective down-regulation of nuclear poly(ADP-ribose) glycohydrolase. [PDF]
The formation of ADP-ribose polymers on target proteins by poly(ADP-ribose) polymerases serves a variety of cell signaling functions. In addition, extensive activation of poly(ADP-ribose) polymerase-1 (PARP-1) is a dominant cause of cell death in ...
