Enables voltage-gated chloride channel activity. Involved in chloride transport and lung development. Located in dendrite and perikaryon. Used to study cystic fibrosis. Human ortholog(s) of this gene implicated in idiopathic generalized epilepsy 11 and primary hyperaldosteronism. Orthologous to human CLCN2 (chloride voltage-gated channel 2).
