1 The suggested mechanism is based on the regulation of local Ca2+ release by cyclic AMP-dependent protein kinase (PKA) and relies upon two experimental observations: first, some G-protein coupled signaling pathways activate PLC and regulate adenylate cyclase at the same time, leading to IP3 production and altering PKA activity via changes in cAMP level; second, phosphorylation by PKA alters the properties of IP3 receptor (IP3R).
