Figure S4. (Related to Fig 5A–C). A set of microtubule inner proteins (MIPs) that have been identified in Chlamydomonas but are absent or could not be identified in Tetrahymena.

(A) The A-tubule “seam” region spanning pf A06∼A10. (B) The ribbon region. (C) The inner junction region. The MIPs in parentheses are consensus MIPs found in both organisms, serving as references here. The arrowheads in the cartoons of DMT indicate the viewing directions.
