Predicted to enable identical protein binding activity. Involved in sensory perception of sound. Located in stereocilium tip. Is expressed in brainstem; metanephros; submandibular gland; and testis. Used to study autosomal dominant nonsyndromic deafness 4A. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 4B and autosomal recessive nonsyndromic deafness 113. Orthologous to human CEACAM16 (CEA cell adhesion molecule 16, tectorial membrane component). [provided by Alliance of Genome Resources, Apr 2022]
