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

As of 2026-09-13

Methionine aminopeptidase 2 shows late clinical disease relevance led by obesity. 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 P50579. Start with obesity, then reuse UniProt P50579 as the stable protein anchor across project notes and exports.

Disease program
obesity

Methionine aminopeptidase 2 shows late clinical disease relevance led by obesity. 1 more disease program remain visible in the same review block. 1 linked drug remains visible in the same block.

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