Has an essential role in the assembly and organization of the sperm flagellar axoneme . Required for the elongation of the primary cilium and sperm flagellar midpiece via modulation of the Notch signaling pathway (By similarity).
Subcellular locations: Cell projection, Cilium, Cell projection, Cilium, Flagellum, Cytoplasm, Cytoskeleton, Microtubule organizing center, Centrosome
Localized to the entire flagellum and predominantly concentrated in the midpiece. Co-localizes with ODFP2 at the centrosome (By similarity).
