FH1FH2 Nucleates Actin Polymerization. (A) Time course of actin polymerization in the presence of FH1FH2 monitored by pyrene fluorescence. Different concentrations of FH1FH2 were added to 2 μM actin (10% pyrene labeled) before initiation of polymerization. a.u., arbitrary units. (B) Nucleation efficiency of FH1FH2. (C) to (E) Fluorescence image of Oregon-green-actin polymerization in the absence and presence of FH1FH2. (C) Oregon-green-actin alone, (D) Oregon-green-actin plus 100 nM FH1FH2, (E) Oregon-green-actin plus 200 nM FH1FH2. Bar in (E) = 5 μm. (F) Time course of actin polymerization in the presence of FH1FH2 and/or OsPRF1. (G) Time course of actin polymerization in the presence of FH1FH2 and/or OsPRF2.
