Figure 4.

Average γ-TuSC map. Each of the reconstructed volumes was segmented into the constant region and the mobile arm, as indicated in Figure 3. An average was calculated for each segment, weighted for class size. In this view, the two average maps are aligned to the corresponding segments of structure 3. The dotted white lines indicate the boundaries used for calculating the approximate volumes of the three segments of the map—115 kDa for each arm and 70 kDa for the body.
