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. {ECO:0000269PubMed:10655058}.
Subcellular Localization Apical cell membrane; Peripheral membrane protein; Extracellular side. Secreted, extracellular space. Note=Found in fiber-like structures during the maturation process of the tectorial membrane.
Disease Associations
Tissue Specificity Expressed specifically in neuroepithelial supporting cells of the inner ear. Expressed in the cochlea between postnatal day P0 and P6 in pseudostratified cells of the greater epithelial ridge, in supporting cells of the neuroepithelium comprising Deiter's, Hensen's, pillar and Claudius cells, in epithelial cells of the Reissner's membrane, in a small set of cells comprising the spiral prominence. Expressed in the cochlea at P15 in interdental cells located underneath the limbal part of the tectorial membrane. Expressed in the vestibular apparatus at P0 in supporting cells of the saccular, utricular maculae and cristae ampullares, in the epithelial cells of the roof of the saccule but not in the roof of the utricle and cristae ampullares (at protein level). Expressed in the cochlea and vestibular organ of the inner ear. {ECO:0000269PubMed:11506947, ECO:0000269PubMed:9405633}.
