WebMar 19, 2024 · Allosteric communication in GPCRs Membrane-bound G protein-coupled receptors (GPCRs) are seven helical proteins that are expressed ubiquitously in multiple cells and hence form the largest family of drug targets. Upon activation by a ligand, GPCRs couple to one or more of the members of the G protein families and/or β-arrestin families.
