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.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the chloride channel (TC 2.A.49) family. ClcB
CC subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL20409.1; Type=Erroneous initiation; Evidence={ECO:0000305};
