Characterization of two classes of small molecule inhibitors of Arp2/3 complex
2009
The actin cytoskeleton plays a critical role in cell biological processes such as cell adhesion, migration and endocytosis. Polymerization of actin filaments directed by the actin-related protein (Arp)2/3 complex supports many types of cellular movement. Two classes of small molecules that bind to different sites on the Arp2/3 complex and inhibit its ability to nucleate actin filaments are now described; these inhibitors provide a powerful approach for studying the Arp2/3 complex in living cells.
