CC -!- FUNCTION: Fluoride-specific ion channel. Important for reducing
CC fluoride concentration in the cell, thus reducing its toxicity.
CC {ECO:0000256|HAMAP-Rule:MF_00454}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=fluoride(in) = fluoride(out); Xref=Rhea:RHEA:76159,
CC ChEBI:CHEBI:17051; Evidence={ECO:0000256|ARBA:ARBA00035585};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:76160;
CC Evidence={ECO:0000256|ARBA:ARBA00035585};
CC -!- ACTIVITY REGULATION: Na(+) is not transported, but it plays an
CC essential structural role and its presence is essential for fluoride
CC channel function. {ECO:0000256|HAMAP-Rule:MF_00454}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00454};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00454}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the fluoride channel Fluc/FEX (TC 1.A.43)
CC family. {ECO:0000256|ARBA:ARBA00035120, ECO:0000256|HAMAP-
CC Rule:MF_00454}.
