CDH23 [ENSP00000381822]
cadherin-like 23; Cadherins are calcium dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells. Cadherin 23 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 (By similarity)
PCDH15 [ENSP00000354950]
protocadherin 15; Calcium-dependent cell-adhesion protein. Essential for maintenance of normal retinal and cochlear function
