Voltage-gated chloride channel. Chloride channels have several functions including the regulation of cell volume; membrane potential stabilization, signal transduction and transepithelial transport. At embryonic stages 13-16, expressed in a subset of the midline cells of the midline primordium and in all of the midline glia. Expressed along the Z-line of the sarcomere in larval longitudinal muscles. Partially edited. Target of Adar. The CLC channel family contains both chloride channels and proton-coupled anion transporters that exchange chloride or another anion for protons. The absence of conserved gating glutamate residues is typical for family members that function as channels. Belongs to the chloride channel (TC 2.A.49) family.
