Neural Wiskott-Aldrich syndrome protein (N-WASP) is the specific ligand for Shigella VirG among the WASP family and determines the host cell type allowing actin-based spreading

Abstract excerpt

Shigella, the causative agent of bacillary dysentery, is capable of directing its movement within host cells by forming an actin comet tail. The VirG (IcsA) pro-tein expressed at one pole of the bacterium recruits neural Wiskott-Aldrich syndrome protein (N-WASP), a member of the WASP family, which in turn stimulates actin-related protein (Arp) 2/3 complex-mediated actin polymerization. As all the WASP family...
