Discrete PIH proteins function in the cytoplasmic preassembly of different subsets of axonemal dyneins

Cross-sectional images of typical axonemes from wild type, pf13 and ida10. In ida10, the inner lobe of the inner arm dynein image, corresponding to the density of single-headed dyneins, is significantly reduced in intensity compared with wild type or pf13. The outer arm dynein is also missing on some outer doublet microtubules.
