Abstract:
Heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptors (GPCRs) control a wide diversity of cellular responses throughout biology. Each GPCR couples to a distinct array of members of the G protein family to control the specificity and diversity of these responses and ultimately determines the therapeutic efficacy of drugs that target these receptors. In this issue of Science Signaling, Masuho et al. developed an approach to broadly defining these GPCR coupling fingerprints.

GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
