Direct actin monomer delivery is a WASP-specific requirement for Arp2/3 complex activation
{{output}}
WASP family proteins activate Arp2/3 complex to nucleate branched actin filaments in diverse cellular processes. To activate, WASP proteins recruit actin monomers to Arp2/3 complex through their conserved WASP homology 2 domains, but how these recruited monome... ...
