  text: Regulation of the Arp2/3 complex is required for productive nucleation of
    branched actin networks. An emerging aspect of regulation is the incorporation
    of subunit isoforms into the Arp2/3 complex. Specifically, both ArpC5 subunit
    isoforms, ArpC5 and ArpC5L, have been reported to fine-tune nucleation activity
    and branch junction stability. We have combined reverse genetics and cellular
    structural biology to describe how ArpC5 and ArpC5L differentially affect cell
    migration. Both define the structural stability of ArpC1 in branch junctions and,
    in turn, by determining protrusion characteristics, affect protein dynamics and
    actin network ultrastructure. ArpC5 isoforms also affect the positioning of members
    of the Ena/Vasodilator-stimulated phosphoprotein (VASP) family of actin filament
    elongators, which mediate ArpC5 isoform–specific effects on the actin assembly
    level. Our results suggest that ArpC5 and Ena/VASP proteins are part of a signaling
    pathway enhancing cell migration.</jats:p>
