Guanine nucleotide-binding protein G(s) subunit alpha isoforms XLas

UniProtKB accession:  Q5JWF2

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. GNAS functions downstream of several GPCRs, including beta-adrenergic receptors. XLas isoforms interact with the same set of receptors as GNAS isoforms (By similarity).
