"along with controlling membrane binding these autoregulatory interactions inhibit the ability of Nwk-SH3a to activate Wiskott-Aldrich syndrome protein (WASp)/actin related protein (Arp) 2/3-dependent actin filament ..we define structural rearrangements in Nwk that control F-BAR-membrane interactions as well as SH3 domain activities and suggest that these two functions are tightly coordinated in vitro and in vivo."xsd:string
