GPCRdb in 2025: adding odorant receptors, data mapper, structure similarity search and models of physiological ligand complexes.
GPCRdb, a key resource for GPCR research, provides reference data, analysis, visualization, experiment design, and dissemination tools. In its sixth major release, GPCRdb now includes all ∼400 human odorant receptors and their orthologs in major model organisms. A new Data Mapper enables users to overlay data onto GPCRs visualized as a wheel, tree, clusters, list, or heatmap. Structure models have been expanded with physiological ligand complexes and updated with state-specific models for all human GPCRs using AlphaFold, RoseTTAFold, and AlphaFold-Multistate. A Structure Similarity Search (via FoldSeek) allows pdb file comparisons across the GPCRdb collection. For ligands, new search tools support queries by name, ID, similarity, or substructure across multiple databases (ChEMBL, Guide to Pharmacology, PDSP Ki, PubChem, DrugCentral, DrugBank).
