Target Interactions
target_interactionsRead-onlyIdempotent
List the quantitative ligand interactions for a protein target in the Guide to PHARMACOLOGY (IUPHAR/BPS). Given a GtoPdb target id (from search_targets), returns the ligands acting on it with interaction type (Agonist/Antagonist/Inhibitor/etc.), action, and binding affinity (e.g. pKi/pIC50). Requires a GtoPdb API key — register free at guidetopharmacology.org/login.jsp and pass your own via _apiKey.
