Actin filaments are organised into sub-compartments of meshwork and bundles in lamellipodia. Localisation of fascin, the LIM and SH3 domain protein 1 (lasp-1), and lasp-2 to the bundles suggest their involvement in that organisation; however, their contributions remain unclear. We have compared the turnover of these proteins with actin at the bundle. After photobleaching, EGFP-actin recovered inwards from the bundle tip, consistent with the retrograde flow by treadmilling. In contrast, the recovery of EGFP-fascin, -lasp-1 and -lasp-2 occurred from the anterograde direction. These results suggest that these molecules would participate in the stabilisation of bundles but not in initiation. (c) 2006 Federation of European Biochemical Societies. Published by Elsevier B.V.
