N terminus of type 5 adenylyl cyclase scaffolds Gs heterotrimer.
According to accepted doctrine, agonist-bound G protein-coupled receptors catalyze the exchange of GDP for GTP and facilitate the dissociation of Galpha and Gbetagamma, which in turn regulate their respective effectors. More recently, the existence of preformed signaling complexes, which may include receptors, heterotrimeric G proteins, and/or effectors, is gaining acceptance. We show herein th...

Stimulation of renin secretion by catecholamines is dependent on adenylyl cyclases 5 and 6.
The sympathetic nervous system stimulates renin release from juxtaglomerular cells via the β-adrenoreceptor-cAMP pathway. Recent in vitro studies have suggested that the calcium-inhibited adenylyl cyclases (ACs) 5 and 6 possess key roles in the control of renin exocytosis. To investigate the relative contribution of AC5 and AC6 to the regulation of renin release in vivo we performed experiments...
متن کاملMolecular and functional diversity of mammalian Gs-stimulated adenylyl cyclases.
Receptor-regulated adenylyl cyclase in mammalian systems is among the best-studied of the cell surface signaling pathways that utilize G-proteins as transducers. In addition to the multiplicity of receptors and Gs proteins that function in this pathway, recent studies have shown that substantial molecular diversity exists in the effector as well. Full-length cDNAs encoding six different G-prote...
متن کاملDistinct mechanisms of regulation by Ca2+/calmodulin of type 1 and 8 adenylyl cyclases support their different physiological roles.
Nine membrane-bound mammalian adenylyl cyclases (ACs) have been identified. Type 1 and 8 ACs (AC1 and AC8), which are both expressed in the brain and are stimulated by Ca(2+)/calmodulin (CaM), have discrete neuronal functions. Although the Ca(2+) sensitivity of AC1 is higher than that of AC8, precisely how these two ACs are regulated by Ca(2+)/CaM remains elusive, and the basis for their divers...
