Unformatted text preview: Largest family of cell surface receptors. Mediate responses to an enormous diversity of extracellular signals including: hormones, local mediators and neurotransmitters. G-protein linked receptors in general consist of a single polypeptide chain that passes 7 times through the lipid bilayer. the ones that arent channels are g protein couples rceptors, the metabotropic glumate recptors; betaadrenergic receptor, receptor for adrenalin G-protein Coupled Receptors Largest family of cell surface receptors. Mediate responses to an enormous diversity of extracellular signals including: hormones, local mediators and neurotransmitters. al little closer to rel strucutre, becuse the protein portion that goes through bilayer are made up of alpha helices G-protein linked receptors in general consist of a single polypeptide chain that passes 7 times through the lipid bilayer. G-protein Coupled Receptors loops on the outside can be of varying sizes; and n terminus can be quite long, or the c terminus can be long and so can interact wi...
