Cell migration occurs through the protrusion of the actin-enrichedlamella. Here, we investigated the effects of RNAi depletionof $~$ 90 proteins implicated in actin function on lamella formationin Drosophila S2 cells. Similar to in vitro reconstitution studiesof actin-based Listeria movement, we find that lamellae formationrequires a relatively small set of proteins that participatein actin nucleation (Arp2/3 and SCAR), barbed end capping (cappingprotein), filament depolymerization (cofilin and Aip1), andactin monomer binding (profilin and cyclase-associated protein).Lamellae are initiated by parallel and partially redundant signalingpathways involving Rac GTPases and the adaptor protein Nck,which stimulate SCAR, an Arp2/3 activator. We also show thatRNAi of three proteins (kette, Abi, and Sra-1) known to copurifywith and inhibit SCAR in vitro leads to SCAR degradation, revealinga novel function of this protein complex in SCAR stability.Our results have identified an essential set of proteins involvedin actin dynamics during lamella formation in Drosophila S2cells.
