This video describes the types of GPCR signalling based on the type of G alpha subunit

GPCR function is associated with cell sensing of external factors including odorants, taste ligands, light, metals, neurotransmitters, biogenic amines, fatty acids, amino acids, peptides, proteins, steroids and other lipids.

PTX ADP-ribosylates inhibitory α-subunits of the heterotrimeric G proteins, thereby perturbing the inhibitory GPCR signaling. iGIST is based on Ligander som fäster vid, och aktiverar, receptorerna innefattar odörer, feromoner, hormoner och signalsubstanser – dessa varierar i storlek från små molekyler till Extracellulär signal --> GPCR --> adenylatcyklas --> cAMP. G-protein a subunit aktiverar adenylatcyklas vilket orskar syntes av cAMP från ATP.

Figure 8.4.12: Signaling Outcomes. The increase in cytosolic calcium ion concentration has various effects, one of which is to activate a protein kinase called protein kinase C (C for calcium), together with the DAG made in the earlier step. However, it has become clear that this greatly oversimplifies the complexities of GPCR signaling (Gurevich & Gurevich 2008). The beta:gamma G-protein dimer is also involved in downstream signaling (Smrcka 2008) and some receptors form metastable complexes with accessory proteins such as the arrestins.

The binding of a signal molecule by the extracellular part of the G-protein linked receptor causes the cytosolic tail of the receptor to interact with, and alter the conformation of, a G-protein. This has two consequences: First, the alpha subunit of the G- protein loses its GDP and binds a GTP instead.

The signal transduction through GPCRs are defined by three essential components: a plasma membrane receptor with seven transmembrane helical segments 4.GPCR signaling mechanism The signals are most commonly transduced by G α, a GTPase switch protein that alternates between an active (“on”) state with bound GTP and inactive (“off”) state with GDP. The other ɤ and β subunits, which remain bound together, occasionally transduce signals. G-protein-coupled receptors (GPCRs) relay numerous extracellular signals by triggering intracellular signaling through coupling with G proteins and arrestins.

G protein-coupled receptors (GPCRs) are cell surface receptors that respond to a wide variety of stimuli, from light, odorants, hormones, and neurotransmitters to proteins and extracellular calcium. GPCRs represent the largest family of signaling proteins targeted by many clinically used drugs. G-protein-coupled receptors (GPCRs) relay numerous extracellular signals by triggering intracellular signaling through coupling with G proteins and arrestins. Recent breakthroughs in the structural determination of GPCRs and GPCR-transducer complexes represent important steps toward deciphering GPCR signal transduction at a molecular level.
