UniProtKB accession:  P04896

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Guanine nucleotide-binding proteins (G proteins) function as transducers in numerous signaling pathways controlled by G protein-coupled receptors (GPCRs). Signaling involves the activation of adenylyl cyclases, resulting in increased levels of the signaling molecule cAMP (PubMed:2022671, PubMed:9395396, PubMed:11087399, PubMed:15591060, PubMed:16766715, PubMed:19243146). GNAS functions downstream of several GPCRs, including beta-adrenergic receptors. Stimulates the Ras signaling pathway via RAPGEF2 (By similarity).
