Mechanism of filament nucleation and branch stability revealed by the structure of the Arp2/3 complex at actin branch junctions.

Actin branch junctions are conserved cytoskeletal elements critical for the generation of protrusive force during actin polymerization-driven cellular motility. Assembly of actin branch junctions requires the Arp2/3 complex, upon activation, to initiate a new actin (daughter) filament branch from th...
