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 P0ABQ4. Use UniProt P0ABQ4 as the stable identity anchor, then attach disease evidence before program review.
Dihydrofolate reductase
Review this target as Dihydrofolate reductase, mapped to UniProt P0ABQ4. Sequence length is 159 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 Dihydrofolate reductase as ChEMBL target CHEMBL1809, mapped to UniProt P0ABQ4. 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.
