Biological Activity

Inhibits neural Wiskott-Aldrich syndrome protein (N-WASP) by stabilizing the autoinhibited state of the protein. Blocks phosphatidylinositol 4,5-bisphosphate (PIP2)-stimulated actin assembly (IC50 ~ 2 μM) but does not directly inhibit actin polymerization.

Technical Data


(Modifications: Phe-2 = D-Phe, Pro-3 = D-Pro, Phe-4 = D-Phe, Pro-6 = D-Pro, Cyclized)

Soluble to 2 mg/ml in water
Desiccate at -20°C
