GPCR Pathway G-protein-coupled receptors (GPCRs) are the largest and most diverse group of membrane receptors in eukaryotes. G proteins are specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP).

In some of the pathways, the effector protein is activated by the free G ɤβ subunit. GPCR signalling mechanism Recent work has shown that Gα can be activated by non-receptor GEFs, which themselves are activated through associations with non-GPCR signaling pathways such as the receptor tyrosine kinase (RTK) pathway (Garcia-Marcos et al., 2015). G protein-coupled receptors (GPCRs) represent the biggest transmembrane receptor family. The Frizzled group of GPCRs is evolutionarily conserved and serves to transduce signals from the Wnt-type lipoglycoprotein growth factors. The Wnt/Frizzled signaling cascades are repeatedly used during animal development and are mostly silent in the adult. GPCR functional selectivity—the process whereby ligands specifically engage distinct signaling pathways—is now a well-established and validated pharmacological concept. Thus, as we and many others have demonstrated, GPCR ligands can be identified which differentially activate canonical G-protein signaling pathways,b-arrestin-mediated signaling and non-G protein/non-arrestin-ergic signaling.

Extracellular signal-regulated kinases are the key downstream mediator for signaling pathways used to activate the receptor. For example, activation of GPCR taking place due to activation of the cAMP-mediated receptor in Dictyostelium discoideum (slime mold), though the alpha and beta subunits of G proteins are absent.

The Wnt/Frizzled signaling cascades are repeatedly used during animal development and are mostly silent in the adult. GPCR functional selectivity—the process whereby ligands specifically engage distinct signaling pathways—is now a well-established and validated pharmacological concept. Thus, as we and many others have demonstrated, GPCR ligands can be identified which differentially activate canonical G-protein signaling pathways,b-arrestin-mediated signaling and non-G protein/non-arrestin-ergic signaling. GPCRs are involved in many diverse signaling events (Kristiansen 2004), using a variety of pathways that include modulation of adenylyl cyclase, phospholipase C, the mitogen activated protein kinases (MAPKs), extracellular signal regulated kinase (ERK) c-Jun-NH2-terminal kinase (JNK) and p38 MAPK.

The signal from the ligand-stimulated GPCR is amplified because the receptor can activate several Gs heterotrimers before it is inactivated. The classical signalling mechanism for G alpha-i (Gi) is inhibition of the cAMP dependent pathway through inhibition of adenylate cyclase (Dessauer et al. 2002). GPCR Signaling Pathway.
