General principles underlying signaling pathways may be gleaned from comparisons of three linear signaling pathways: the G protein-coupled (α1-adrenergic, M-1 muscarinic, V-1 vasopressin) receptor–G q –phospholipase-C pathway, the receptor tyrosine kinase-Ras-mitogen-activated protein kinase (MAPK) pathway, and the cytokine receptor–Janus kinase (Jak)–Stat3 pathway.

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. GPCR Signaling Pathway (Concept Id: C1517369) A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex.
Signaling by G protein coupled receptor The way the signals are transduce is different in various intracellular pathways that transduce signals downstream from activated cell-surface receptors. G protein coupled receptors indirectly activate enzymes that generate intracellular second messengers as mentioned above. Overview of GPCR, Calcium, cAMP Signaling Resources, interactive pathway diagrams, and other technical resources. Upon ligand binding, GPCRs undergo a conformational change, catalyzing Gα to exchange GDP for GTP (guanosine-5’-triphosphate). Then, GTP-bound Gα and Gβγ dissociate from the GPCR and activate downstream signaling effectors. Hydrolysis of Gα-GTP to Gα-GDP causes the reassociation of the heterotrimeric G-protein with the GPCR.

The three best characterized Wnt signaling pathways are the canonical Wnt pathway, the noncanonical planar cell polarity pathway, and the noncanonical Wnt/calcium pathway. As their names suggest, these pathways belong to one of two categories: canonical or noncanonical.
