PORCN (porcupine homolog – Drosophila) is a human gene.[1][2] The protein is homologous to other membrane-bound O-acyltransferases.

Function

The protein encoded by this gene is an endoplasmic reticulum transmembrane protein involved in processing of wingless proteins such as WNT7A.[2]

Clinical significance

Mutations in this gene are associated with focal dermal hypoplasia.[3]

Mutations in PORCN are associated to Goltz-Gorlin syndrome .[4]

Ligands

Inhibitors

  • WNT974 (LGK-974) - 1243244-14-5, researched for anti-cancer effects in Wnt-pathway sensitive tumours.[5] Also investigated for influencing cardiac tissue remodelling following infarction.[6]
