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

As of 2026-09-14

Neuraminidase shows approved-linked disease relevance led by influenza. 5 more disease programs remain visible in the same review block. 5 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P03474. Start with influenza, then reuse UniProt P03474 as the stable protein anchor across project notes and exports.

Neuraminidase shows approved-linked disease relevance led by influenza. 5 more disease programs remain visible in the same review block. 5 linked drugs remain visible in the same block.

Start review with influenza because it currently carries approved-linked support. Linked drugs include INFLUENZA B VIRUS, INACTIVATED NEURAMINIDASE, LANINAMIVIR OCTANOATE, OSELTAMIVIR PHOSPHATE, PERAMIVIR. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
