Function

Component of the tectonic-like complex, a complex localized at the transition zone of primary cilia and acting as a barrier that prevents diffusion of transmembrane proteins between the cilia and plasma membranes. {ECO:0000250}.

Subcellular Localization

Cytoplasm, cytoskeleton, cilium basal body. Cell junction, adherens junction.

Disease Associations

Joubert syndrome 3 (JBTS3) [MIM:608629]: A disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy and renal disease. Joubert syndrome type 3 shows minimal extra central nervous system involvement and appears not to be associated with renal dysfunction. {ECO:0000269PubMed:15322546, ECO:0000269PubMed:15467982, ECO:0000269PubMed:16453322, ECO:0000269PubMed:22425360, ECO:0000269PubMed:23532844}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Highly expressed in the most primitive normal hematopoietic cells. Expressed in brain, particularly in neurons that give rise to the crossing axons of the corticospinal tract and superior cerebellar peduncles. Expressed in kidney (renal collecting duct cells) (at protein level). {ECO:0000269PubMed:14751929, ECO:0000269PubMed:15322546, ECO:0000269PubMed:18633336}.
