Figure 7.

Model for cytoplasmic cilia maturation. The kl-granule (light purple) localizes immediately proximal to the ciliary cap (orange) and transition zone (green) within the cytoplasmic compartment. Constituent mRNAs (purple) are likely locally translated (ribosomes, lime green), and their proteins (axonemal dyneins, yellow) are incorporated into the axoneme (blue) as the microtubules are displaced from the ciliary cap. In this way, cytoplasmic cilia maturation is progressive, with axonemal proteins being added to the bare microtubules as elongation proceeds.
