Binding of ActA and ActA derivatives to Arp2/3 complex–coated resin. Equimolar concentrations of ActA or the indicated ActA derivatives were incubated with anti-p41-Arp2/3–coated resin or control IgG–coated resin. Bound ActA and ActA derivatives were resolved on a 7% polyacrylamide gel and visualized by Western blotting with polyclonal anti-ActA antibody. The expected mobility of ActA and Δ31-262 is indicated by a star.
