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 O60674. Use UniProt O60674 as the stable identity anchor, then attach disease evidence before program review.
Tyrosine-protein kinase JAK2
Review this target as JAK2/TYK2, mapped to UniProt O60674. ChEMBL maps the protein component as Tyrosine-protein kinase JAK2. Sequence length is 1132 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 JAK2/TYK2 as ChEMBL target CHEMBL3301392, mapped to UniProt O60674. 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.
