Frame the target before identity details

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

As of 2026-09-13

Mitogen-activated protein kinase 8 shows clinical signal disease relevance led by idiopathic pulmonary fibrosis. 1 more disease program remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P45983. Start with idiopathic pulmonary fibrosis, then reuse UniProt P45983 as the stable protein anchor across project notes and exports.

Disease program
idiopathic pulmonary fibrosis

Mitogen-activated protein kinase 8 shows clinical signal disease relevance led by idiopathic pulmonary fibrosis. 1 more disease program remain visible in the same review block. 1 linked drug remains visible in the same block.

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