The IUPHAR/BPS Guide to PHARMACOLOGY (GtoPdb) Reference Ingest Guide

Source Information

InfoRes ID: infores:gtopdb

Description: The IUPHAR/BPS Guide to PHARMACOLOGY (GtoPdb; https://www.guidetopharmacology.org) is an open-access, expert-curated, online database that provides succinct overviews and key references for pharmacological targets and their recommended experimental ligands. It includes over 3039 protein targets and 12,163 ligand molecules, including approved drugs, small molecules, peptides and antibodies. GtoPdb) was established and developed by the International Union of Basic and Clinical Pharmacology (IUPHAR) and the British Pharmacological Society (BPS). It originated from the IUPHAR-DB, a former resource focused on receptors and channels that was first compiled in 2003 and from the BPS‘ Guide to Receptors and Channels’, a compendium of a wider range of targets than those originally covered in IUPHAR-DB

Ingest Information

Ingest Categories: primary_knowledge_provider

Utility: The International Union of Basic and Clinical Pharmacology (IUPHAR) / British Pharmacological Society (BPS) Guide to PHARMACOLOGY is an expert-curated resource of ligand-activity-target relationships, the majority of which come from high-quality pharmacological and medicinal chemistry literature.

Scope: GtoPdb includes over 3039 protein targets and 12,163 ligand molecules, including approved drugs, small molecules, peptides and antibodies.

Included Content

File Name Included Records Fields Used
interactions.csv No filtering. Records for all species included. Note however that records in the data describe results of a single published experiment. In our ingest records with the same ligand, target, and type + action are merged into a single edge, and metadata from each merged record (publications) combined into a list and attached to the edge. Ligand Id, Target Species, Type, Target Ensembl Gene ID
targets_and_families.csv subject: ChemicalEntity, MolecularMixture, SmallMolecule; object: Gene; Predicate: directly_physically_interacts_with Type, Family id, Family name, Target id, Target name, Subunit id, Subunit name, Target systematic name, Target abbreviated name, synonyms, HGNC id, HGNC symbol, HGNC name, Human genetic localisation, Human nucleotide RefSeq, Human protein RefSeq, Human SwissProt, Human Entrez Gene, Human Ensembl Gene, RGD id, RGD symbol, RGD name, Rat genetic localisation, Rat nucleotide RefSeq, Rat protein RefSeq, Rat SwissProt, Rat Entrez Gene, Rat Ensembl Gene, MGI id, MGI symbol MGI name Mouse genetic localisation Mouse nucleotide RefSeq Mouse protein RefSeq Mouse SwissProt Mouse Entrez Gene Mouse Ensembl Gene

Filtered Content

File Name Filtered Records Rationale
peptides.csv remove records with species in: Mouse, Rat, Pig, Bovine, Sheep, Bovine, Dog, Rabbit, European common frog, Rhesus macaque Only include records with Human in Species

Future Content Considerations

edge_content: Consider ingest the file 'approved_drug_primary_target_interactions.csv' which contains approved drugs detailed interactions list

edge_content: Consider ingest peptides.csv with species other than Human

edge_property_content: Longer term, consider creating ExperimentalStudyResult objects to capture metadata for each experiment that supports an edge (e.g. affinity data, assay descriptions, and associated publications)
