Configurational diversity of metabotropic glutamate receptor complexes with beta-arrestins
Beta-arrestins (β-arrs) are cytosolic proteins which mediate G protein-coupled receptor (GPCR) desensitization, endocytosis, and signaling. Despite the widespread physiological roles of β-arr coupling, the molecular basis of GPCR/β-arr interaction has been studied primarily in monomeric family A GPCRs. Here we develop...
