CC -!- FUNCTION: Strongly outwardly rectifying, electrogenic
CC H(+)/Cl(-)exchanger which mediates the exchange of chloride ions
CC against protons (By similarity). The CLC channel family contains both
CC chloride channels and proton-coupled anion transporters that exchange
CC chloride or another anion for protons (By similarity). The presence of
CC conserved gating glutamate residues is typical for family members that
CC function as antiporters (By similarity). {ECO:0000250|UniProtKB:P51790,
CC ECO:0000250|UniProtKB:P51791}.
CC -!- SUBUNIT: Monomer and homodimer (By similarity). Forms heterodimers with
CC CLCN4 (By similarity). {ECO:0000250|UniProtKB:P51791}.
CC -!- SUBCELLULAR LOCATION: Early endosome membrane
CC {ECO:0000250|UniProtKB:P51790}; Multi-pass membrane protein
CC {ECO:0000255}. Late endosome membrane {ECO:0000250|UniProtKB:P51790};
CC Multi-pass membrane protein {ECO:0000255}. Lysosome membrane
CC {ECO:0000250|UniProtKB:P51791}; Multi-pass membrane protein
CC {ECO:0000255}. Cell membrane {ECO:0000250|UniProtKB:P51792}; Multi-pass
CC membrane protein {ECO:0000255}.
CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:P51790}.
CC -!- SIMILARITY: Belongs to the chloride channel (TC 2.A.49) family. ClC-
CC 3/CLCN3 subfamily. {ECO:0000305}.
