- Stimulating Arp2/3 complex activity
- Isolating Arp2/3 complex from cell or tissue extract
Material
The VCA (Verprolin, cofilin, acidic) domain of human WASP protein has been expressed in a bacterial expression system as a GST-tagged fusion protein. The protein has been purified by glutathione affinity chromatography and is supplied as a lyophilized powder. When reconstituted with distilled water, the complex is in the following buffer: 20 mM Tris pH 7.5, 25 mM KCl, 1 mM MgCl2, 0.5 mM EDTA, 0.2% dextran, 2% sucrose. The molecular weight of the GST-VCA domain protein is approximately 43 kDa.
Purity
Purity is determined by scanning densitometry of proteins on SDS-PAGE gels. Samples are >95% pure.
Biological Activity
VCG03 was tested in an actin polymerization assay (Cat. # BK003). In conjunction with Arp2/3 (Cat. # RP01) it was shown to stimulate actin polymerization 20-fold compared to the control without VCG03. This indicates VCA domain specificity for stimulating the actin nucleating activity of Arp2/3.
