Figure 4

Tomogram from a Tetrahymena cilium. Isosurface renderings show the averaged 96-nm axonemal repeats of the Radial Spoke proteins. Radial spoke proteins 1, 2, and 3 are shown in green, blue, and orange, respectively. The ODA are shaded in purple, IDA are shaded in light pink, and yellow shading indicates the Nexin-Dynein Regulatory Complex. The red arrowheads indicate the connections between the radial spokes. (A) is a longitudinal-front view, (B) longitudinal back view, and (C) a bottom view. Adapted from [28], with permission.
