A ribose-functionalized NAD+ with unexpected high activity and selectivity for protein poly-ADP-ribosylation. [PDF]
Nicotinamide adenine dinucleotide (NAD+)-dependent ADP-ribosylation plays important roles in physiology and pathophysiology. It has been challenging to study this key type of enzymatic post-translational modification in particular for protein poly-ADP ...

A systematic analysis of the PARP protein family identifies new functions critical for cell physiology [PDF]
The poly(ADP-ribose) polymerase (PARP) family of proteins use NAD[superscript +] as their substrate to modify acceptor proteins with ADP-ribose modifications. The function of most PARPs under physiological conditions is unknown.

Prospects for non-immunological molecular therapeutics in melanoma [PDF]
In 2006 there were 60,000 new cases of cutaneous melanoma in the European Union and 13,000 deaths (www.europeancancerleagues.org). Currently available systemic treatment options for metastatic melanoma, including both cytotoxic and immunologic therapies,

Proteomic Investigation of Phosphorylation Sites in Poly(ADP-ribose) Polymerase-1 and Poly(ADP-ribose) Glycohydrolase [PDF]
Phosphorylation is a very common post-translational modification event known to modulate a wide range of biological responses. Beyond the regulation of protein activity, the interrelation of phosphorylation with other post-translational mechanisms is responsible for the control of diverse signaling pathways.

Poly(ADP-ribose) Polymerase-1 (PARP1) in Atherosclerosis: From Molecular Mechanisms to Therapeutic Potential [PDF]
Poly(ADP-ribosyl)ation reactions, carried out by poly(ADP-ribose) polymerases (PARPs/ARTDs), are reversible posttranslational modifications impacting on numerous cellular processes (e.g., DNA repair, transcription, metabolism, or immune functions). PARP1

Regulation of Rad52-dependent replication fork recovery through serine ADP-ribosylation of PolD3
Although Poly(ADP-ribose)-polymerases (PARPs) are key regulators of genome stability, how site-specific ADP-ribosylation regulates DNA repair is unclear.

Basal Activity of a PARP1-NuA4 Complex Varies Dramatically across Cancer Cell Lines
Poly(ADP-ribose) polymerases (PARPs) catalyze poly(ADP-ribose) addition onto proteins, an important posttranslational modification involved in transcription, DNA damage repair, and stem cell identity.

Aag-initiated base excision repair promotes ischemia reperfusion injury in liver, brain, and kidney [PDF]
Inflammation is accompanied by the release of highly reactive oxygen and nitrogen species (RONS) that damage DNA, among other cellular molecules. Base excision repair (BER) is initiated by DNA glycosylases and is crucial in repairing RONS-induced DNA ...

It takes two to tango: NAD+ and sirtuins in aging/longevity control [PDF]
The coupling of nicotinamide adenine dinucleotide (NAD+) breakdown and protein deacylation is a unique feature of the family of proteins called ‘sirtuins.’ This intimate connection between NAD+ and sirtuins has an ancient origin and provides a ...
