Distributions of secondary structures and conserved domains in Tetrahymena nucleoporins. Each Nup is shown as the protein name on the left. Blue, red and black letters denote MIC-specific, MAC-specific and shared components, respectively. Asterisks indicate Nups that are newly identified in this study. The colored components in the illustration are as follows: orange boxes/bars, α-helix; green boxes/bars, β-strand; red slanting lines, FG repeats; blue slanting lines, FX repeats (X means any residue, but the majority are N and Q); purple ellipses, predicted TM domain. Conserved domains are indicated by differently colored bars with standard domain names.
