title: N-WASP generates a buzz at membranes on the move.
abstract: The fast-growing ends of actin filaments push against membranes to create cell-surface protrusions and to propel the movement of membrane vesicles. Co et al. (2007) now show that the neural Wiskott-Aldrich syndrome protein (N-WASP) mediates dynamic attachment between membranes and the growing ends of actin filaments to sustain membrane movement.
