Predicted to enable collagen binding activity; identical protein binding activity; and myosin binding activity. Involved in retina development in camera-type eye. Located in stereocilium and synapse. Colocalizes with several cellular components, including neuronal cell body; photoreceptor connecting cilium; and photoreceptor inner segment. Human ortholog(s) of this gene implicated in Usher syndrome (multiple); nonsyndromic deafness; and retinitis pigmentosa (multiple). Orthologous to human USH2A (usherin).
