Including closely related subtype homology models, this coverage amounts to approximately 12% of the human GPCR superfamily. 2007-04-01 · Structure-based analysis of GPCR function: conformational adaptation of both agonist and receptor upon leukotriene B4 binding to recombinant BLT1 J.

Structural Features of GPCRs The GPCR structures share a similar overall architecture that consists of a canonical seven transmembrane (7TM) a-helical G-Protein-Coupled Receptor GPCR is most abundant and largest superfamily of receptors. It mediate most cellular responses to hormones and neurotransmitters In the past five years, the field of GPCR structure has exploded. GPCRs (G protein-coupled receptors) are small membrane-spanning proteins, with most of their surface buried inside the membrane. This makes them notoriously difficult to crystallize. Several viruses also encode chemokines and chemokine receptors to subvert the host immune response. How protein ligands activate GPCRs remains unknown. We report the crystal structure at 2.9 angstrom resolution of the human cytomegalovirus GPCR US28 in complex with the chemokine domain of human CX3CL1 (fractalkine).

Recent breakthroughs in the structural determination of GPCRs and GPCR-transducer complexes represent important steps toward deciphering GPCR signal transduction at a molecular level. Our understanding of GPCR structure is based largely on the high-resolution structures of the inactive state of rhodopsin. Rhodopsin is better suited for structural studies than most other GPCRs because it is possible to obtain large quantities of highly enriched protein from bovine retina.
