Abstract

The Arp2/3 complex, a 220 kDa macromolecular assembly comprising two actin-related proteins and five other subunits, plays a key role in cellular motility by initiating the polymerization of new actin filaments. Crystal and cryo-electron microscopic structures of the Arp2/3 complex and branch junctions have clarified extensive biochemical data on the mechanism of this process.
