Cyclic adenosine diphosphate-ribose is the most potent Ca2+-mobilizing second messenger known. It has been shown to mobilize intracellular Ca2+ stores in invertebrate as well as mammalian cells at low nanomolar concentrations. cADPR may function as an endogenous modulator of Ca2+-induced Ca2+ release.
