Fig. 1. Overall architecture of the CNC.
(A) Domain structures of the yeast coat nups and sAB-57. Black lines indicate the crystallized fragments. U: unstructured, D: domain invasion motif, VH: heavy chain variable region, CH: heavy chain constant region, VL: light chain variable region, CL: light chain constant region. (B) Reconstitution of the yeast CNC•sAB-57, lacking Nup133. Elution profiles from a Superdex 200 10/300 column are shown for Nup120•Seh1•Nup85 (Trimer 1), Sec13•Nup145C•Nup84NTD (Trimer 2), CNC, and CNC•sAB-57 (left). SDS-PAGE gel of the reconstituted CNC•sAB-57 used for crystallization (right). (C) Cartoon and schematic representations of the yeast CNC•sAB-57 crystal structure viewed from two sides.
