Figure 6. Fitting of the composite H. sapiens Y-complex into the cryo-ET map of the entire NPC.
(a) Consensus map calculated from the cryo-ET map of the human NPC (EMD code: 2444)15. The cytoplasmic ring density is highlighted in grey for clarity. (b) The top scoring fit of the composite H. sapiens Y-complex (conformation 1) and the second top scoring fit (conformation 2) are depicted. (c) A superposition of the two fits from (b) shows that they are related by a ~20° rotation about the Y-complex hub, and substantial bending of the long stack.
