As of 2026-09-14

Angiopoietin-1 receptor shows approved-linked disease relevance led by cancer. 5 more disease programs remain visible in the same review block. 6 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt Q02763. Start with cancer, then reuse UniProt Q02763 as the stable protein anchor across project notes and exports.

Angiopoietin-1 receptor shows approved-linked disease relevance led by cancer. 5 more disease programs remain visible in the same review block. 6 linked drugs remain visible in the same block.

Start review with cancer because it currently carries approved-linked support. Linked drugs include ALTIRATINIB, CEP-11981, FORETINIB, GLESATINIB. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
