Mobilization of intracellular calcium from the sarcoplasmic reticulum of B-lymphocytes using cyclic guanosine 3'5'-monophosphate (cGMP).
Cyclic guanosine-3'5' monophosphate (cGMP) can mobilize intracellular calcium from the microsomal fraction of B-lymphocytes of the mouse spleen as a result of activation of cGMP-dependent microsomal proteinkinases. The existence of such a mechanism makes B-lymphocytes independent of extracellular calcium in response to agents whose effect on B-lymphocytes is mediated by calcium mechanisms.
