Accessory proteins in the biogenesis of G protein-coupled receptors
1Department of Pharmacology, University of California, Irvine 92697, USA.
Abstract:
Intracellular accessory proteins can be critical for G protein-coupled receptor (GPCR) biogenesis, including aspects of GPCR trafficking. Recent discoveries include the identification of multiple membrane-associated proteins that dictate not only the intracellular sequestration and/or transport of GPCRs, but also modulate-quite dramatically-GPCR ligand specificity subsequent to delivery to the cell surface. These exciting discoveries have shifted earlier paradigms of GPCR functionality.

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...
