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 Cysteine protease as ChEMBL target CHEMBL4751, mapped to UniProt Q95WR6. 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.
