Frame the target before identity details
Structured disease, protein, and project context should read before the lower-level identity rail.
As of 2026-09-13Protein identity stays anchored to UniProt Q29463. Use UniProt Q29463 as the stable identity anchor, then attach disease evidence before program review.
Anionic trypsin
Review this target as Trypsin II, mapped to UniProt Q29463. ChEMBL maps the protein component as Anionic trypsin. Sequence length is 247 aa.
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 Trypsin II as ChEMBL target CHEMBL4472, mapped to UniProt Q29463. 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.
