Frame the target before identity details
Structured disease, protein, and project context should read before the lower-level identity rail.
As of 2026-09-14Protein identity stays anchored to UniProt Q6B856. Use UniProt Q6B856 as the stable identity anchor, then attach disease evidence before program review.
Tubulin beta-2B chain
Review this target as Tubulin beta chain, mapped to UniProt Q6B856. ChEMBL maps the protein component as Tubulin beta-2B chain. Sequence length is 445 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 Tubulin beta chain as ChEMBL target CHEMBL3394, mapped to UniProt Q6B856. 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.
