Poly(ADP-ribosylation) is a post-translational modification of proteins playing a crucial role in DNA repair, replication, transcription and cell death. In this paper, the main features of this process have been reviewed, focusing on the best known poly(ADP-ribose) polymerizing enzyme, PARP-1, a DNA nick-sensor protein that uses beta-NAD+ to form polymers of ADP-ribose. The modulation of poly(ADP-ribosylation) during apoptosis and the possible effects of its inhibition on cell metabolism are discussed.

Abstract
Poly(ADP-ribosylation) is a post-translational modification of proteins playing a crucial role in DNA repair, replication, transcription and cell death. In this paper, the main features of this process have been reviewed, focusing on the best known poly(ADP-ribose) polymerizing enzyme, PARP-1, a DNA nick-sensor protein that uses beta-NAD+ to form polymers of ADP-ribose. The modulation of poly(ADP-ribosylation) during apoptosis and the possible effects of its inhibition on cell metabolism are discussed.File in questo prodotto:
