UniProt Annotation
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. Regulator of Hedgehog (Hh), required for both activation and inhibition of the Hh pathway in the patterning of the neural tube. During neural tube development, it is required for formation of the most ventral cell types and for full Hh pathway activation. Functions in Hh signal transduction to fully activate the pathway in the presence of high Hh levels and to repress the pathway in the absence of Hh signals. Modulates Hh signal transduction downstream of SMO and RAB23 (By similarity). {ECO:0000250}.
Subcellular Localization Cytoplasm, cytoskeleton, cilium basal body {ECO:0000250}. Secreted {ECO:0000305}. Note=Despite the presence of a signal sequence, the full length protein might not be secreted. Localizes at the transition zone, a region between the basal body and the ciliary axoneme. {ECO:0000250}.
Disease Associations Joubert syndrome 13 (JBTS13) [MIM:614173]: 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. {ECO:0000269PubMed:21725307}. Note=The disease is caused by mutations affecting the gene represented in this entry.
