Wiskott-Aldrich syndrome protein family member 2WASP family protein member 2, Protein WAVE-2, Verprolin homology domain-containing protein 2, WASF2,
Wiskott-Aldrich syndrome proteins (WASPs) mediate actin dynamics by activating the Arp2/3 actin nucleation complex in response to activated Rho family GTPases. In mammals, five WASP family members have been described. Hematopoietic WASP and ubiquitously expressed N-WASP are autoinhibited in unstimulated cells.
