Enables chloride channel activity. Predicted to be involved in chloride transport and sensory perception of sound. Predicted to act upstream of or within several processes, including auditory receptor cell stereocilium organization; diet induced thermogenesis; and neuromuscular process controlling balance. Located in stereocilium bundle. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 103. Orthologous to human CLIC5 (chloride intracellular channel 5).
