As of 2026-09-14

Protein-serine O-palmitoleoyltransferase porcupine shows clinical signal disease relevance led by squamous cell carcinoma. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt Q9H237. Start with squamous cell carcinoma, then reuse UniProt Q9H237 as the stable protein anchor across project notes and exports.

squamous cell carcinoma

Protein-serine O-palmitoleoyltransferase porcupine shows clinical signal disease relevance led by squamous cell carcinoma. 1 linked drug remains visible in the same block.

Start review with squamous cell carcinoma because it currently carries clinical signal support. Linked drugs include WNT-974. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
