Figure 8. Unique carboxyl terminal domain (CTD).
Comparison of the CTD orientations in SMYD1 (magenta) and SMYD3 in cross-eye stereo. The larger loop structure in SMYD1 (indicated by the arrow) forces the CTD assembly to shift such that the C-terminus no longer contacts the MYND domain, as in SMYD3. The contacts between the two domains lie within the red circle.
