Figure 2.
(a) ACE1 crown-crown interaction between Nup145C and Nup84. (b) The same interaction between two Sec31 molecules (PDB 2PM6; ref. 36). The Sec31 interaction is shown without domain swapping, and the rest of the molecules are removed for clarity (see Results). Analogous juxtaposition of crown helices 6, 7 and 8 is observed in both a and b.
