Target data Guanine nucleotide-binding proteins (G proteins) function as transducers in numerous signaling pathways controlled by G protein-coupled receptors (GPCRs) (PubMed : 12391161, PubMed : 17110384, PubMed : 21488135, PubMed : 26206488, PubMed : 8702665, PubMed : 10200251). The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state (PubMed : 12391161, PubMed : 17110384, PubMed : 10200251). Signaling by an activated GPCR promotes GDP release and GTP binding (PubMed : 12391161, PubMed : 17110384, PubMed : 10200251). The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal (PubMed : 12391161, PubMed : 17110384, PubMed : 10200251). Both GDP release and GTP hydrolysis are modulated by numerous regulatory proteins (PubMed : 12391161, PubMed : 17110384, PubMed : 10200251). Signaling involves the activation of adenylyl cyclases, resulting in increased levels of the signaling molecule cAMP (PubMed : 17110384, PubMed : 26206488, PubMed : 26206488, PubMed : 8702665). Functions downstream of beta-adrenergic receptors (PubMed : 21488135). Stimulates the Ras signaling pathway via RAPGEF2 (PubMed : 12391161). See full target information GNAS
