摘要: Cyclic ADP-ribose (cADPR), an endogenous modulator of ryanodine receptor Ca(2+)-releasing channels, is found in various tissues. Cytosolic injection cADPR induces elevation intracellular Ca(2+) concentrations or potentiates increases. facilitates neurotransmitter insulin release and modifies ionic currents. synthesized by ADP-ribosyl cyclase metabolized hydrolase. activity up-regulated nitric oxide/cyclic GMP-dependent phosphorylation stimulation via G-proteins within membranes. These findings suggest that a second messenger cellular signaling. However, many intriguing issues remain to be addressed before this identity confirmed.
