Popis: Structural advances in our understanding of the functions of the actin cytoskeleton have come from diverse sources. On the one hand, the determination of the structure of a bacterial actin-like protein MreB reveals the prokaryotic origins of the actin cytoskeleton, whereas on the other, cryo-electron microscopy and crystallography have yielded reconstructions of many actin crosslinking, regulatory and binding proteins in complex with F-actin. Not least, a high-resolution structure of the Arp2/3 complex and a reconstruction with F-actin provides considerable insight into the eukaryotic machinery, vital for the formation of new F-actin barbed ends, a prerequisite for rapid actin polymerisation involved in cell shape change and motility.
