Wnt Inhibitor IWP-4 was identified in a high throughput screen for antagonists of the Wnt / β-catenin pathway. Wnt Inhibitor IWP-4 prevents palmitylation of Wnt proteins by Porcupine (Porcn), a membrane-bound O-acyltransferase, there by blocking Wnt secretion and activity. It also blocks phosphorylation of the Lrp6 receptor and accumulation of both Dvl2 and β-catenin¹.

New 50 mg size now available.
