RA Fernandez-Castano Merediz E., Dyer J., Salmon K.S.H., Shirazi-Beechey S.P.;
RT "Molecular characterisation of fructose transporter (GLUT5) in equine small
RT intestine.";
RL Submitted (APR-2003) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Functions as a fructose transporter that has only low
CC activity with other monosaccharides. Can mediate the uptake of
CC deoxyglucose, but with low efficiency. Essential for fructose uptake in
CC the small intestine. Plays a role in the regulation of salt uptake and
CC blood pressure in response to dietary fructose. Required for the
CC development of high blood pressure in response to high dietary fructose
CC intake. {ECO:0000250|UniProtKB:P43427, ECO:0000250|UniProtKB:Q9WV38}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-fructose(out) = D-fructose(in); Xref=Rhea:RHEA:60372,
CC ChEBI:CHEBI:37721; Evidence={ECO:0000250|UniProtKB:P22732};
CC -!- SUBCELLULAR LOCATION: Apical cell membrane
CC {ECO:0000250|UniProtKB:Q9WV38}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:Q9WV38}. Cell membrane
CC {ECO:0000250|UniProtKB:Q9WV38}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:Q9WV38}. Cell membrane, sarcolemma
CC {ECO:0000250|UniProtKB:P43427}. Note=Localized on the apical membrane
CC of jejunum villi, but also on lateral plasma membranes of the villi.
CC Transport to the cell membrane is dependent on RAB11A.
CC {ECO:0000250|UniProtKB:Q9WV38}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily. Sugar
CC transporter (TC 2.A.1.1) family. Glucose transporter subfamily.
CC {ECO:0000305}.
