Function

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. {ECO:0000269PubMed:18385425, ECO:0000269PubMed:19944400, ECO:0000269PubMed:19944405}.

Subcellular Localization

Cell projection, cilium {ECO:0000269PubMed:18385425}. Cytoplasm {ECO:0000269PubMed:18385425}. Cytoplasm, cytoskeleton, spindle pole {ECO:0000269PubMed:18385425}. Note=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.

Disease Associations

Ciliary dyskinesia, primary, 13 (CILD13) [MIM:613193]: A disorder characterized by abnormalities of motile cilia. Respiratory infections leading to chronic inflammation and bronchiectasis are recurrent, due to defects in the respiratory cilia; reduced fertility is often observed in male patients due to abnormalities of sperm tails. Half of the patients exhibit randomization of left-right body asymmetry and situs inversus, due to dysfunction of monocilia at the embryonic node. Primary ciliary dyskinesia associated with situs inversus is referred to as Kartagener syndrome. At ultrastructural level, CILD13 is characterized by a marked reduction or absence of both dynein arms from the patients cilia. {ECO:0000269PubMed:19944400, ECO:0000269PubMed:19944405}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Mainly expressed in trachea and testis. {ECO:0000269PubMed:19944405}.
