WebAll adenylyl cyclases are activated by both forskolin (a diterpene extracted from plants) or GTP-bound Gαs (GTP/Gαs). Adenylyl cyclase is inhibited by adenosine analogues termed P-site inhibitors such as 2′-deoxy-3′-cAMP. In addition, Ca 2+ /calmodulin can activate some isoforms (Table 1). The membrane-bound adenylyl cyclases have ... WebAdenylate cyclase 1 is stimulated by G s alpha. Strong synergy between G s alpha and Ca/CaM for adenylate cyclase 1 activation is basis for the co-incident detection of signals between G s and calcium pathways. Adenylate cyclase 1 is strongly inhibited by G protein betagamma subunits Tang and Gilman (1991).
