Activated receptors (R*) can then activate heterotrimeric G proteins (com-posed of a. Members of this seven α-helical transmembrane protein family transduce the extracellular signals and regulate intracellular second messengers through coupling to heterotrimeric G-proteins, adenylate cyclase, cAMPs, and protein .Membrane proteins expressed at the cell surface act as a communication interface between the external and internal environments of a cell. The intracellular transmission of the extracellular signal is mediated by the selective coupling of GPCRs to G proteins, which, in turn, activate downstream effectors. Because of possible database errors in downloadable material, as well as ambiguity of ligand-target interactions in certain sources, we manually curated each druggable GPCR to verify pharmacological interaction of the approved drugs.
