G protein-coupled receptors (GPCRs) are cell-surface receptors mediating the responses of 2/3rds of human hormones1 and 1/3rd of drugs2. Each GPCR can bind several transducers, G proteins, GPCR kinases (GRKs) and arrestins leading to distinct intracellular signaling networks and functional outcomes.
