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

As of 2026-09-13

Mitogen-activated protein kinase kinase kinase 1 shows clinical signal disease relevance led by psoriasis. 2 more disease programs remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt Q13233. Start with psoriasis, then reuse UniProt Q13233 as the stable protein anchor across project notes and exports.

Disease program
psoriasis

Mitogen-activated protein kinase kinase kinase 1 shows clinical signal disease relevance led by psoriasis. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with psoriasis because it currently carries clinical signal support. Linked drugs include E-6201. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
