Protein source · UniProt accession via ChEMBL component mappingCross-source identity
Keep the review anchor, source IDs, and context contract aligned before reusing this target elsewhere.
This review treats Translocator protein as ChEMBL target CHEMBL4552, mapped to UniProt P16257. Disease framing currently uses the Open Targets-ready proxy contract.
Reuse the same identifiers in notes, watch rules, exports, and review packs so provenance stays stable across surfaces.
