A " tubulin acetyltransferase " is located in the axoneme, and acetylates the ?-tubulin subunit in an assembled microtubule.
12.
The majority of epididymal axonemes showed structural defects, most commonly loss of a single microtubule doublet at a conserved position within the axoneme.
13.
Thought to be important in regulating the motion of the axoneme, this " T "-shape complex projects from each set of outer doublets toward the central microtubules.
14.
The microtubules of the flagellar axoneme lie in the normal 9 + 2 arrangement, orientated with the + at the anterior end and the-in the basal body.
15.
Radial spoke protein complexes form part of the axoneme of eukaryotic flagella and are located between the axoneme's outer ring of doublet microtubules and central pair of microtubules.

17.
The spoke stalk binds to the A-tubule of each microtubule outer doublet, and the spoke head faces in towards the center of the axoneme ( see illustration at right ).
18.
When this is carried out in a synchronized fashion, with the microtubules on one side of the axoneme being pulled'down'and those on the other side pulled'up,'the axoneme as a whole can bend back and forth.

20.
Each heavy chain has a globular motor domain with a doughnut-shaped structure believed to resemble that of other AAA proteins, a coiled coil " stalk " that binds to the microtubule, and an extended tail ( or " stem " ) that attaches to a neighboring microtubule of the same axoneme.
