Gelsolin (top) was the first member of the group to be sequenced (Kwiatkowski).  Its six domains are a repeat of two sets of three in that G1 (dark blue) is most like G4 (light blue), G2 like G5, and G3, like G6 (Way & Weeds, 1988).  The villin group are characterised by the possesion of the villin head piece (Purple oblong) at the C-terminus. One of the most divergent forms is EhABPH from Entamoeba histolytica (Ebert et al, 2000) which has a coronon-like N-terminal region followed by gelsolin/villin domain but lacking G1.
