Web21 jun. 2010 · Ligand binding disrupts an ionic lock between the E/DRY motif of TM-3 and acidic residues of TM-6. As a result the GPCR reorganizes to allow activation of G-alpha proteins. The side perspective is a view from above and to the side of the GPCR as it is set in the plasma membrane (the membrane lipids have been omitted for clarity). Web25 sep. 2024 · GPCRs are membrane-embedded receptors arranged in seven helical transmembrane domains (labelled TM1 to TM7) followed by a shorter helix ... through a network of hydrophobic residues. The ionic lock maintaining the receptor in its inactive form is disrupted, leading to an increase of the inter-helix distances (notably TM3-TM6).
