Bioactivity
Wnt signaling proteins are small secreted proteins that are active in embryonic development, tissue homeostasis, and tumorigenesis. Wnt proteins bind to receptors on the cell surface, initiating a signaling cascade that leads to beta-catenin activation of gene transcription. IWP-4 is an inhibitor of Wnt production that impairs Wnt pathway activity in vitro with an IC50 value of 25 nM. IWP-4 inactivates Porcupine, a membrane-bound O-acyltransferase responsible for palmitoylating Wnt proteins, which is essential for their signaling ability and secretion. At 5 muM, IWP-4 has been shown to block Wnt-dependent phosphorylation of the low-density lipoprotein receptor-related protein 6 receptor and the scaffold protein Dishevelled, preventing the accumulation of beta-catenin. This compound has been used to induce cardiomyocyte differentiation from human pluripotent stem cells.

Product Notes
The IWP 4 (Catalog #AAA5750097) is an Inhibitor and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "IWP 4, Inhibitor" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
