RL J. Biol. Chem. 290:19874-19887(2015).
CC -!- FUNCTION: Fluoride channel required for the rapid expulsion of
CC cytoplasmic fluoride. {ECO:0000269|PubMed:24173035,
CC ECO:0000269|PubMed:26055717}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:26055717};
CC Multi-pass membrane protein {ECO:0000269|PubMed:26055717}.
CC -!- DISRUPTION PHENOTYPE: Highly sensible to fluoride, but not to other
CC halide salts. The growth of a double deletion of both FEX1 and FEX2 is
CC inhibited at almost a 1000-fold lower fluoride concentration than in
CC the wild-type. Has increased intracellular fluoride concentrations.
CC {ECO:0000269|PubMed:24173035}.
CC -!- MISCELLANEOUS: Present with 220 molecules/cell in the plasma membrane.
CC {ECO:0000269|PubMed:26055717}.
CC -!- SIMILARITY: Belongs to the fluoride exporter Fluc/FEX family.
CC {ECO:0000305}.
