Cyclic ADP-ribose (cADPR), an endogenous modulator of ryanodine receptor Ca2+-releasing channels, is found in various tissues. Cytosolic injection of cADPR induces an elevation of intracellular Ca2+ concentrations or potentiates Ca2+ increases. cADPR facilitates neurotransmitter or insulin release and modifies ionic currents. cADPR is synthesized by ADP-ribosyl cyclase and is metabolized by cADPR hydrolase. ADP-ribosyl cyclase activity is up-regulated by nitric oxide/cyclic GMP-dependent phosphorylation or receptor stimulation via G-proteins within membranes. These findings suggest that cADPR is a second messenger in cellular Ca2+ signaling. However, many intriguing issues remain to be addressed before this identity is confirmed.
