Two genes from the Arp2/3 complex with a recent gene duplication in Chlorarachniophyta. (A) Phylogeny of Arp2 (39 taxa, 373 AA), and (B) phylogeny of APRC1 (34 taxa, 328 AA). Coloring of groups in both phylogenies as in figure 1 (Brown = Foraminifera, red= Radiolaria, yellow = Endomyxa, and blue= Filosa). Thick branches represent bootstrap support > 75% and posterior probability > 0.9 and the scale bar equals 0.2 substitutions per site. (C) Molecular model and comparison of conserved residues between the two paralogs of Arp2 a and b superimposed on PDB accession 4JD2. (D) The Arp2/3 complex (PDB accession 4JD2) showing the position of arp2 (red) and ARPC1 (green) relative to the other molecules in the complex. (E) Molecular model and comparison of conserved residues between the two paralogs of ARPC1 a and b superimposed on PDB accession 4JD2. For figures C and E coloring display areas uniquely conserved in either paralog a (red) or paralog b (blue) or areas that are shared between the paralogs (green). Both Arp2 and ARPC1 are shown from two different sides (displayed in upper and lower panels).
