CC   -!- FUNCTION: Important for reducing fluoride concentration in the cell,
CC       thus reducing its toxicity. {ECO:0000255|HAMAP-Rule:MF_00454}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00454}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00454}.
CC   -!- SIMILARITY: Belongs to the CrcB (TC 9.B.71) family. {ECO:0000255|HAMAP-
CC       Rule:MF_00454}.
