Enables voltage-gated chloride channel activity. Involved in chloride transport. Predicted to be located in sarcolemma. Predicted to be part of chloride channel complex. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in myotonia congenita. Orthologous to human CLCN1 (chloride voltage-gated channel 1).
