Figure 1 Overall three-dimensional structure of RCC1. Ribbon diagram of the RCC1 propeller structure as viewed along (a) or perpendicular to (b) the central shaft. The blades (a) are numbered (B1-B7) along the sequence. Semiconserved histidines that connect the blades and invariant residues believed to be important for the interaction with Ran are shown as ball-and-stick representations.
