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

As of 2026-09-13

Inhibitor of nuclear factor kappa-B kinase subunit beta shows late clinical disease relevance led by Autosomal dominant polycystic kidney disease. 5 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 O14920. Start with Autosomal dominant polycystic kidney disease, then reuse UniProt O14920 as the stable protein anchor across project notes and exports.
