GPCRs are a large family of membrane-embedded receptors, with structural features that have been preserved through the course of evolution. This model represents the shared structural features of all GPCRs.

2019年6月10日 · Class B G protein-coupled receptors (GPCRs) are important therapeutic targets for major diseases. Here, we present structures of peptide and Gs-bound pituitary adenylate cyclase-activating peptide, PAC1 receptor, and corticotropin-releasing …

GPCRdb in 2025: adding odorant receptors, data mapper, structure similarity search and models of physiological ligand complexes. An online GPCR structure analysis platform. GPCR drug discovery: new agents, targets and indications. Generic GPCR residue numbers - aligning topology maps while minding the gaps.

GPCR-EXP is a database that specializes in curating experimental and predicted structures of G protein-coupled receptors (GPCR). Structure-related data for experimental structures, such as resolution, publication information, and biological ligand, from the Protein Databank (PDB) are extracted and incorporated into the database.

A pipeline for computational modeling and simulation of G-Protein Coupled Receptors (GPCRs) and other membrane proteins. To model a membrane protein look for the navigation bar at the top of the page and click on Model a Membrane Protein.

By comparing the different GPCR structures, researchers at the PSI GPCR Network have revealed a few common themes in their form and function, as shown here on the beta2 adrenergic receptor (PDB entry 2rh1). As expected, all have the characteristic seven alpha helices passing up and down through the membrane, connected by loops that extend into ...

2023年7月15日 · Protein Structure Network (PSN) analysis is a cutting-edge approach to investigate bio-macromolecular function. psnGPCRdb stores single, difference, and consensus structure networks of all GPCRs in the PDB. psnGPCRdb allows to graphically analyze 3D-structure networks together with interactive data-tables.

The latest release of GPCRdb offers access to a variety of updated and new experimentally derived data: (i) All GPCR crystal structures in the PDB, as well as 309 ligand fragments from crystal structures that may be used to build new pharmacophores or even de novo ligands; (ii) The largest collection of GPCR single-point mutations, which may ...

2018年7月4日 · There are now more than 200 reported GPCR structures (PDB entries) from more than 50 unique receptors, including full-length structures from members of classes A, B and F, and incomplete (7TMD or...

G Protein-Coupled Receptors (GPCRs) are transmembrane (TM) proteins that span the cell membrane seven times, and contain intracellular and extracellular domains, comprised of connecting loops, as well as terminal extension sequences. GPCRs bind ligands within their transmembrane and/or extracellular domains.
