Rocket-based motility: a universal mechanism?

Abstract

Similarities between actin polymerization at the leading edges of motile mammalian cells and the motile actin tail of the bacterium Listeria monocytogenes are centred on the Arp2/3 complex. Eukaryotic cells use multiple pathways to modulate actin polymerization, while Listeria short-circuits these pathways to produce constitutive actin polymerization.
