Abstract

F-actin's secondary structure Filamentous F-actin, an essential contractile component of muscle fibres and a major component of the cytoskeleton, is formed through polymerization of globular G-actin. In this study, Keiichi Namba and colleagues report the structure of F-actin by electron cryomicroscopy and build a complete atomic model of F-actin. This new structure will aid in our understanding of the mechanism of actin assembly and disassembly.
