Predicted to enable identical protein binding activity. Predicted to be involved in auditory receptor cell stereocilium organization and sensory perception of sound. Predicted to act upstream of or within auditory receptor cell development; detection of mechanical stimulus involved in sensory perception of sound; and establishment of protein localization. Predicted to be located in nucleoplasm; stereocilia ankle link; and stereocilium. Predicted to be part of USH2 complex and stereocilia ankle link complex. Predicted to be active in cilium; plasma membrane; and stereocilium tip. Human ortholog(s) of this gene implicated in Usher syndrome type 2A; Usher syndrome type 2C; and autosomal recessive nonsyndromic deafness 57. Orthologous to human PDZD7 (PDZ domain containing 7).
