For 10 points, name these microtubule structures that are found in centrosomes, which serve as attachment points for the mitotic spindle and have a 9+3 structure.
The size of these objects which are NOT found outside the cell is regulated by Orofaciodigital Syndrome 1 protein. The stabilization and formation of these structures is aided by ANA2. In C. Elegans, formation of these objects requires ZYG-1 to phosphorylate SAS-6, but in humans the ZYG-1 is replaced in its role by PLK4. These cellular components have 9 fold symmetry and are replicated once per cell cycle. These objects are found in a larger structure along with the gamma-tubulin ring complex. These objects and basal bodies have a similar structure and composition.
