G protein-coupled receptors (GPCRs) consist of seven transmembrane domains (TMs), which are connected via intra- and extracellular protein domains.
WebG-protein-coupled receptors (GPCRs) are the largest human receptor family and involved in virtually every physiological process. One hallmark of their function is specific coupling to selected signaling pathways. The ability to tune this coupling would make development of receptors with new capabilities possible.
