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

Replicase polyprotein 1ab shows approved-linked disease relevance led by COVID-19. 5 more disease programs remain visible in the same review block. 3 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P0DTD1. Start with COVID-19, then reuse UniProt P0DTD1 as the stable protein anchor across project notes and exports.

COVID-19

Replicase polyprotein 1ab shows approved-linked disease relevance led by COVID-19. 5 more disease programs remain visible in the same review block. 3 linked drugs remain visible in the same block.

Start review with COVID-19 because it currently carries approved-linked support. Linked drugs include GALIDESIVIR, REMDESIVIR, RO-0622. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
