Required for axonemal dynein assembly and ciliary motility in ciliated organs, including Kupffer's vesicle, during embryogenesis. Facilitates the onset of robust cilia motility during development.
Subcellular locations: Cytoplasm, Cytoskeleton, Flagellum basal body, Cytoplasm, Cytoskeleton, Flagellum axoneme
Expression is concentrated at the flagellum basal body but is also detected along the length of the flagellum.
