Predicted to enable chloride channel activity. Acts upstream of or within cilium assembly and pronephros development. Predicted to be located in cytoplasm and membrane. Predicted to be part of chloride channel complex. Is expressed in digestive system; immature eye; pectoral fin bud; pleuroperitoneal region; and sensory system. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 103. Orthologous to human CLIC5 (chloride intracellular channel 5).
