The function of RTK–GPCR signalling platforms can be modulated with conformational-specific inhibitors that stabilise defined GPCR states to abrogate both GPCR agonist- and growth factor-stimulated cell responses. Sphingosine 1-phosphate and platelet-derived growth factor (PDGF) act via PDGF beta receptor-sphingosine 1-phosphate receptor complexes in airway smooth muscle cells. Uncovering G protein-coupled receptor kinase-5 as a histone deacetylase kinase in the nucleus of cardiomyocytes.

Receptor tyrosine kinase–G-protein-coupled receptor signalling platforms: out of the shadow? Selective ligand-induced stabilization of active and desensitized parathyroid hormone type 1 receptor conformations. 3A). GPCR ligand-dependent transactivation of RTKs It is well established that G-protein-coupled receptor (GPCR) ligands and growth factors that bind to receptor tyrosine kinases (RTKs) activate overlapping signalling pathways. Question: What Are The Similarities And Differences Between G-protein Coupled Receptors (GPCRs) & Receptor Tyrosine Kinases (RTK) ? Compare and contrast GPCR and RTK receptors with respect to (a) structure-especially the transmembrane region, (b) activation mechanism, (c) initial signal transduction across the membrane. Platelet-derived growth factor stimulation of the p42/p44 mitogen-activated protein kinase pathway in airway smooth muscle: role of pertussis-toxin-sensitive G-proteins, c-Src tyrosine kinases and phosphoinositide 3-kinase. provide evidence that dopamine signaling through the D4 receptor, a G protein-coupled receptor, may activate the receptor tyrosine kinase (RTK) platelet-derived growth factor receptor β (PDGFRβ) to mediate inhibition of N-methyl-D-aspartate receptor (NMDAR) activity. Distinct conformational changes in beta-arrestin report biased agonism at seven-transmembrane receptors.
