CC   -!- FUNCTION: Probably acts as an electrical shunt for an outwardly-
CC       directed proton pump that is linked to amino acid decarboxylation, as
CC       part of the extreme acid resistance (XAR) response. {ECO:0000255|HAMAP-
CC       Rule:MF_01203}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01203}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01203}.
CC   -!- SIMILARITY: Belongs to the chloride channel (TC 2.A.49) family. ClcB
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01203}.
