Abstract

Adenosine 5'-diphosphate (ADP)-ribosylation is a protein posttranslational modification that is catalyzed by ADP-ribosyltransferases (ARTs), using nicotinamide adenine dinucleotide (NAD(+)) as a substrate. Mono-ribosylation can be extended into polymers of ADP-ribose (PAR). Poly(ADP-ribosyl)polymerase (PARP) 1, the best-characterized cellular enzyme catalyzing this process, is the prototypical member of a family of mono- and poly(ADP-ribosyl)transferases. The physiological consequences of ADP-ribosylation are inadequately understood. PARP2010, the 18th International Conference on ADP-Ribosylation, attracted scientists from all over the world to Zurich, Switzerland. Highlights from this meeting include promising clinical trials with PARP inhibitors and new insights into cell, structural, and developmental biology of ARTs and the (glyco)hydrolase proteins that catalyze de-ADP-ribosylation of mono- or poly-ADP-ribosylated proteins. Moreover, potential links to the NAD-dependent sirtuin family were explored on the basis of a shared dependence on cellular NAD(+) concentrations and the relationship of ADP-ribosylation with intermediary metabolism and cellular energetics.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
