Protocol: The International Union of Basic and Clinical Pharmacology/British Pharmacological Society (IUPHAR/BPS) Guide to PHARMACOLOGY Database (GtoPdb) uses expert subcommittees to collate peer-reviewed information from the published literature regarding individual protein targets, and describes the pharmacology, genetics, function and anatomy of each target. Its pages provide a richly curated overview of the pharmacology of receptors, ion channels, enzymes and other target types, which can be found by following the external link to the GtoPdb website.

Comment: The data collected focuses on ligands at human receptors. Data are provided at rat or mouse orthologues where there are significant species differences, or where data are not yet available at the human target.

Information on individual experimental protocols can be found in the primary references listed for each ligand.

Affinity data are expressed as pKi [-log(Ki)], pKd [-log(Kd)], pIC50 [-log(IC50)], pEC50 [-log(EC50)], pKB [-log(KB)], pA2 or as a micromolar concentration range. In most cases the original concentration can be found in the primary reference.
