Predicted to enable actin filament binding activity and microfilament motor activity. Acts upstream of or within inner ear morphogenesis; locomotory behavior; and sensory perception of sound. Located in stereocilium. Is expressed in several structures, including heart; inner ear; liver; metanephros; and skeletal muscle. Used to study autosomal recessive nonsyndromic deafness 3. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 3 and sensorineural hearing loss. Orthologous to human MYO15A (myosin XVA).
