Abstract excerpt
Cyclic ADP-ribose (cADPR) is a universal calcium messenger molecule that regulates many physiological processes. The production and degradation of cADPR are catalyzed by a family of related enzymes, including the ADP-ribosyl cyclase from Aplysia california (ADPRAC) and CD38 from human. Although ADPRC and CD38 share a common evolutionary ancestor, their enzymatic functions toward NAD and cADPR homeostasis have...
