187-1, N-WASP inhibitor

Pricing Availability Delivery Time Qty
Cat.No. 2067 - 187-1, N-WASP inhibitor | cyclo(Lys-D-Phe-D-Pro-D-Phe-Phe-D-Pro-Gln)2 | CAS No. 380488-27-7
Description: N-WASP inhibitor; inhibits actin assembly

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.
