Novel GPCR structures Although GPCRs account for ~30% of marketed drug targets, these account for only a small portion of potentially therapeutically important receptors. For many receptors, no structures current exist or the available structures are confined to a single receptor state (most also with only a …

GPCRdb contains reference data, interactive visualisation and experiment design tools for G protein-coupled receptors (GPCRs). GPCRdb curates sequence alignments, structures and receptor mutations from literature. Interactive diagrams visualise receptor residues (e.g. snakeplot and helix box plot) and relationships (e.g phylogenetic trees). Briefly, an equidistantly placed quartet of each GPCR structure is simulated in a membrane environment composed of 63 different lipid types and stretched in a 40 × 40 nm2surface area in the lateral dimension.

In 2000, the first crystal structure of a mammalian GPCR, that of bovine rhodopsin(1F88), was solved. In 2007, the first structure of a human GPCR was solved This human β2-adrenergic receptorGPCR structure proved highly similar to the bovine rhodopsin. The structures of activated or agonist-bound GPCRs have also been determined.

For multiple domain GPCRs, structural models are built by GPCR-I-TASSER for each domain separately which are then reassembly by the I-TASSER approach. All the models are finally subjected to FG-MD for fragment-guided molecular dynamic simulation refinements. The recent breakthroughs in GPCR crystallography have led to widespread adoption of structure-based drug design methodologies for GPCR targets.

Activation of G protein-coupled receptors (GPCRs) initiates conformational shifts that trigger interaction with a specific G-protein subtype from a structurally homologous set. A major unsolved problem is the mechanism by which this selectivity is achieved. Structures of GPCR–G protein complexes so far fail to reveal the origin of selectivity because they all involve one G-protein subtype

GPCR structural studies have revealed the general bases of receptor activation, and browsing appropriate experimental conditions for structure studies.

Overall, the structure does provide some additional insight into the diversity of the GPCR-G protein interactions and highlights a possible novel interaction with the Rho C-term and the heterotrimer. However, there is really a lack of experimental data to both validate the structural model and also to provide some functional relevance of this potentially interesting interaction.
