Abstract
G protein-coupled receptors (GPCRs) have a simple seven transmembrane helix architecture which has evolved to recognize a diverse number of chemical signals. The more than 800 GPCRs encoded in the human genome function as receptors for vision, smell and taste, and mediate key physiological processes. Consequently, these receptors are a major target for pharmaceuticals. Protein crystallography and electron cryo-microscopy have provided high resolution structures of many GPCRs in both active and inactive conformations. However, these structures have not sparked a surge in rational drug design, in part because GPCRs are inherently dynamic and the structural changes induced by ligand or drug binding to stabilize inactive or active conformations are often subtle rearrangements in packing or hydrogen-bonding interactions. NMR spectroscopy provides a sensitive probe of local structure and dynamics at specific sites within these receptors as well as global changes in receptor structure and dynamics. These methods can also capture intermediate states and conformations with low populations that provide insights into the activation pathways. We review the use of solid-state magic angle spinning NMR to address the structure and activation mechanisms of GPCRs. The focus is on the large and diverse class A family of receptors. We highlight three specific class A GPCRs in order to illustrate how solid-state, as well as solution-state, NMR spectroscopy can answer questions in the field involving how different GPCR classes and subfamilies are activated by their associated ligands, and how small molecule drugs can modulate GPCR activation.

Abstract
![]()
This
review focuses on the construction and application of structural chemokine
receptor models for the elucidation of molecular determinants of chemokine
receptor modulation and the structure-based discovery and design of
chemokine receptor ligands. A comparative analysis of ligand binding
pockets in chemokine receptors is presented, including a detailed
description of the CXCR4, CCR2, CCR5, CCR9, and US28 X-ray structures,
and their implication for modeling molecular interactions of chemokine
receptors with small-molecule ligands, peptide ligands, and large
antibodies and chemokines. These studies demonstrate how the integration
of new structural information on chemokine receptors with extensive
structure–activity relationship and site-directed mutagenesis
data facilitates the prediction of the structure of chemokine receptor–ligand
complexes that have not been crystallized. Finally, a review of structure-based
ligand discovery and design studies based on chemokine receptor crystal
structures and homology models illustrates the possibilities and challenges
to find novel ligands for chemokine receptors.
