Protein: Cadherin-23 (Otocadherin) (Q9H251)
Organism: Homo sapiens (Human)
Function: Cadherins are calcium-dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells. CDH23 is required for establishing and/or maintaining the proper organization of the stereocilia bundle of hair cells in the cochlea and the vestibule during late embryonic/early postnatal development. It is part of the functional network formed by USH1C, USH1G, CDH23 and MYO7A that mediates mechanotransduction in cochlear hair cells. Required for normal hearing.
Subcellular location: Cell membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000255}.
