  • Berriman and coworkers write of trypanosomes: The proteins of the flagellar axoneme appeared to be extremely well conserved.

  • Thus, the 9+2 axoneme, which arose very early in eukaryotic evolution, appears to be constructed around a core set of proteins that are conserved in organisms possessing flagella and cilia Berriman, M., et al.

    The Edge of Evolution Michael J. Behe 2007

  • Essentially, a multiprotein system known as intraflagellar transport, or IFT, attaches to the cilium axonome (the 9+2 structure made of microtubules, which are made of tubulin), grabs the necessary protein subunits (like tubulin) from inside the cell, and “walks” them along the axoneme of the cilium out to the tip, where the subunits are deposited.
