Physiology of ADP-ribosylation

ADP-ribosylation of proteins is a versatile post-translational modification that can alter the chemistry of a specific side chain or provide a handle for the binding of a recognition domain. A better understanding of ADP-ribosylating enzymes and their targets is opening new therapeutic opportunities. This minireview series focuses on physiological aspects of ADP-ribosylation, while a companion series focuses on drug targets.
