Phospho-selective mechanisms of arrestin conformations and functions revealed by unnatural amino acid incorporation and 19 F-NMR
2015
G-protein-coupled receptors (GPCRs) signal via G proteins or arrestin-mediated pathways; the plasticity of arrestin proteins is thought to underlie their function. Here, the authors use NMR to examine how β-arrestin-1 recognizes different GPCR phospho-barcodes, and how this triggers structural rearrangements to fulfill selective functions.
