Regulation of branched versus linear Arp2/3-generated actin filaments
Abstract
Activation of the Arp2/3 complex by VCA-motif-bearing actin nucleation-promoting factors results in the formation of “daughter” actin filaments branching off the sides of pre-existing “mother” filaments. Alternatively, when stimulated by SPIN90, Arp2/3 directly nucleates “linear” actin…
