Biochem/physiol Actions

IWP-4 blocks Wnt family member 5a. It blocks Wnt protein secretion and prevents the canonical and non-canonical signaling pathways.
IWP-4 is a potent inhbitor of the Wnt pathway regulatory protein porupine (Porcn). IWP-4 blocks palmitylation, and subsquent secretion and activity of Wnt. IWP-4 induces the differentiation of human pluripotent stem cells into cardiomyocytes.
