Abstract:
The dominance of G protein-coupled receptors (GPCRs) as a drug target class, coupled with the increased pace of target identification and expansion of compound libraries, presents a compelling need to develop technologies to screen multiple GPCRs simultaneously. To address this need, GPCR microarrays that require the co-immobilization of lipid molecules and the probe receptors of interest have been fabricated, using conventional robotic printing technologies. Assays to screen compounds for their pharmacological properties (binding affinity, relative potency and selectivity) using GPCR microarrays are discussed.

G Protein-coupled Receptors
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...
