title: Signalling to actin: the Cdc42-N-WASP-Arp2/3 connection.
abstract: The molecular link between the signalling pathway regulating the formation of filopodia and the initiation of local actin polymerization has been elucidated: N-WASP, a close homologue of WASP, which is the product of the gene responsible for the Wiskott-Aldrich syndrome, mediates a direct connection between the small G-protein Cdc42 and the Arp2/3 complex.
