CC   -!- FUNCTION: Plasma membrane transporter mediating the uptake by cells of
CC       the water soluble vitamin B2/riboflavin that plays a key role in
CC       biochemical oxidation-reduction reactions of the carbohydrate, lipid,
CC       and amino acid metabolism. {ECO:0000250|UniProtKB:Q9NQ40}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=riboflavin(in) = riboflavin(out); Xref=Rhea:RHEA:35015,
CC         ChEBI:CHEBI:57986; Evidence={ECO:0000250|UniProtKB:Q9NQ40};
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the riboflavin transporter family.
CC       {ECO:0000305}.
