Frame the target before identity details
Structured disease, protein, and project context should read before the lower-level identity rail.
As of 2026-09-14Dual specificity protein kinase TTK shows clinical signal disease relevance led by cancer. 2 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P33981. Start with cancer, then reuse UniProt P33981 as the stable protein anchor across project notes and exports.
Dual specificity protein kinase TTK shows clinical signal disease relevance led by cancer. 2 linked drugs remain visible in the same block.
Start review with cancer because it currently carries clinical signal support. Linked drugs include BAY-1161909, BAY-1217389. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
