Protein Structure
UniProt Annotation
Function Glycoprotein specific to acellular membranes of the inner ear. May be required for the anchoring of the otoconial membranes and cupulae to the underlying neuroepithelia in the vestibule. May be involved in the organization and/or stabilization of the fibrillar network that compose the tectorial membrane in the cochlea. May play a role in mechanotransduction processes (By similarity). {ECO:0000250}.
Subcellular Localization Apical cell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Extracellular side {ECO:0000250}. Secreted, extracellular space {ECO:0000250}. Note=Found in fiber-like structures during the maturation process of the tectorial membrane. {ECO:0000250}.
Disease Associations Deafness, autosomal recessive, 18B (DFNB18B) [MIM:614945]: A form of non-syndromic deafness characterized by a moderate hearing impairment, which can be associated with vestibular dysfunction, and a flat to shallow "U" or slightly downsloping shaped audiograms. {ECO:0000269PubMed:23122587}. Note=The disease is caused by mutations affecting the gene represented in this entry.
