Cilium-specific protein required for the stability of the ciliary architecture. Plays a role in cytoplasmic preassembly of dynein arms. Involved in regulation of microtubule-based cilia and actin-based brush border microvilli.
Subcellular locations: Cell projection, Cilium, Cytoplasm, Cytoplasm, Cytoskeleton, Spindle pole
In HEK293T cells, it is diffusely cytoplasmic and concentrates at the mitotic spindle poles, while in MDCK cells, it localizes in the cilium. In vivo, this protein is probably restricted to the cilium.
Mainly expressed in trachea and testis.
