| 产品介绍 | background:
Defects in TCTN2 are the cause of Meckel syndrome type 8 (MKS8) [MIM:613885]. A disorder characterized by a combination of renal cysts and variably associated features including developmental anomalies of the central nervous system (typically encephalocele), hepatic ductal dysplasia and cysts, and polydactyly.
Function:
Component of the tectonic-like complex, a complexlocalized at the transition zone of primary cilia and acting as abarrier that prevents diffusion of transmembrane proteins betweenthe cilia and plasma membranes. Required for hedgehog signalingtransduction (By similarity).
Subunit:
Part of the tectonic-like complex (also named B9 complex)(By similarity).
Subcellular Location:
Membrane; Single-pass type I membraneprotein (Potential). Cytoplasm, cytoskeleton, cilium basal body (Bysimilarity). Note=Localizes at the transition zone, a regionbetween the basal body and the ciliary axoneme (By similarity).
DISEASE:

A disorder characterized by a combination ofrenal cysts and variably associated features includingdevelopmental anomalies of the central nervous system (typicallyencephalocele), hepatic ductal dysplasia and cysts, andpolydactyly.
Note=Defects in TCTN2 may be a cause of Joubert syndrome,a disorder presenting with cerebellar ataxia, oculomotor apraxia,hypotonia, neonatal breathing abnormalities and psychomotor delay.Neuroradiologically, it is characterized by cerebellar vermianhypoplasia/aplasia, thickened and reoriented superior cerebellarpeduncles, and an abnormally large interpeduncular fossa, givingthe appearance of a molar tooth on transaxial slices (molar toothsign). Additional variable features include retinal dystrophy andrenal disease.
Similarity:
Belongs to the tectonic family.
