Biological Activity

Inhibitor of neural Wiskott-Aldrich syndrome protein (N-WASP) activity. Interacts with the regulatory GTPase-binding domain of N-WASP; inhibits activation of Arp2/3 complex by maintaining N-WASP in an inactive conformation. Also inhibits PIP2-induced actin polymerization (EC50 ~ 4μM).

Compound Libraries

Wiskostatin is also offered as part of the Tocriscreen Plus. Find out more about compound libraries available from Tocris.
