Villin is an F-actin nucleating, crosslinking, severing, and capping protein within the gelsolin superfamily. We have used electron tomography of 2D arrays of villin-crosslinked F-actin to generate 3D images revealing villin's crosslinking structure. In these polar arrays, neighboring filaments are spaced 125.9 +/- 7.1 angstrom apart, offset axially by 17 angstrom, with one villin crosslink per actin crossover. More than 6500 subvolumes containing a single villin crosslink and the neighboring actin filaments were aligned and classified to produce 3D subvolume averages. Placement of a complete villin homology model into the average density reveals that full-length villin binds to different sites on F-actin from those used by other actin-binding proteins and villin's close homolog gelsolin.
