WebMar 14, 2003 · Gs-coupled receptor signaling in airway smooth muscle. Gs-coupled receptors on airway smooth muscle (ASM) are activated by endogenous agents such as circulating catecholamines, prostaglandins and iso-prostanes, adenosine and vasoactive intestinal peptide (VIP). ... direct contribution of non-GPCR signaling pathways to … WebG i alpha subunit. G. i. alpha subunit. Gi protein alpha subunit is a family of heterotrimeric G protein alpha subunits. This family is also commonly called the Gi/o ( Gi /Go ) family or Gi/o/z/t family to include closely related family members. G alpha subunits may be referred to as G i alpha, G αi, or G i α.
WebG protein-coupled receptors (GPCRs) are a large family of cell surface receptors that share a common structure and method of signaling. The members of the GPCR family all have … WebThe signal transduction pathways of Gs, Gi and Gq protein families are widely studied, whereas signaling properties of G12 proteins are only emerging. Many GPCRs were found to couple to G12/13 proteins in addition to coupling to one or more other types of G proteins. G12/13 proteins couple GPCRs to activation of the small monomeric GTPase RhoA.
WebThe cAMP Gs cell line overexpresses a wild-type GPCR coupled with natural Gs, and is designed to detect the increase in intracellular cAMP levels in response to stimulation by receptor agonists.These cell lines are designed to be used in conjunction with the cAMP Assay test kit. The cAMP cell line is a non-force-coupled Gs and Gi stable clonal ... The Gs alpha subunit (Gαs, Gsα) is a subunit of the heterotrimeric G protein Gs that stimulates the cAMP-dependent pathway by activating adenylyl cyclase. Gsα is a GTPase that functions as a cellular signaling protein. Gsα is the founding member of one of the four families of heterotrimeric G proteins, defined by … See more The general function of Gs is to activate intracellular signaling pathways in response to activation of cell surface G protein-coupled receptors (GPCRs).
