Post-translational modification of proteins with ADP-ribose alters their physical and functional characteristics. The relationship between ADP-ribosylation and several bacterial toxins (e.g. cholera toxin, pertussis toxin, diphtheria toxin) is well established. In contrast, the function of the endogenous ADP-ribosyl transferase enzyme is poorly understood. The latter statement also applies to poly(ADP-ribose) polymerase, although PARP has become familiar due to its association with apoptosis. This article summarizes the enzymology of ADP-ribosylation, reviews the various cellular processes in which it may participate and examines the possible functions of ADP-ribosylation in cardiovascular tissues. Poly(ADPribosyl)ation, which has been linked to ischemia-reperfusion injury, is known to participate in DNA repair. In contrast, mono (ADP-ribosyl) ation is best known for modulating G protein function. In the cardiovascular system, mono (ADP-rib osyl) ation may exert effects by modifying growth factors or by transducing the intracellular effects of nitric oxide. Alternatively, mono (ADP-ribosyl) ation could influence cell migration by modifying cytoskeletal proteins. By also examining the role of ADP-ribosylation in other systems, considerable insight into the possible contributions of ADP-ribosylation to cardiovascular function can be extrapolated to both normal and pathological conditions.
