Frame the target before identity details

Structured disease, protein, and project context should read before the lower-level identity rail.

As of 2026-09-14

Tyrosinase shows clinical signal disease relevance led by freckles. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P14679. Start with freckles, then reuse UniProt P14679 as the stable protein anchor across project notes and exports.

freckles

Tyrosinase shows clinical signal disease relevance led by freckles. 1 linked drug remains visible in the same block.

Start review with freckles because it currently carries clinical signal support. Linked drugs include ARBUTIN. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
