Accessory proteins in the biogenesis of G protein-coupled receptors
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.
