CC -!- FUNCTION: Facilitative glucose transporter that can also mediate the
CC uptake of various other monosaccharides across the cell membrane.
CC Mediates the uptake of glucose, 2-deoxyglucose, galactose, mannose,
CC xylose and fucose, and probably also dehydroascorbate. Does not mediate
CC fructose transport. {ECO:0000250|UniProtKB:P11169}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glucose(out) = D-glucose(in); Xref=Rhea:RHEA:60376,
CC ChEBI:CHEBI:4167; Evidence={ECO:0000250|UniProtKB:P11169};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-galactose(in) = D-galactose(out); Xref=Rhea:RHEA:34915,
CC ChEBI:CHEBI:4139; Evidence={ECO:0000250|UniProtKB:P11169};
CC -!- ACTIVITY REGULATION: Deoxyglucose transport is inhibit by D-glucose, D-
CC galactose and maltose. Galactose transport is inhibited by D-glucose
CC and maltose. {ECO:0000250|UniProtKB:P11169}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P11169};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:P11169}. Perikaryon
CC {ECO:0000250|UniProtKB:Q07647}. Cell projection
CC {ECO:0000250|UniProtKB:Q07647}. Note=Localized to densely spaced
CC patches along neuronal processes. {ECO:0000250|UniProtKB:Q07647}.
CC -!- TISSUE SPECIFICITY: Detected in stomach, placenta, lung and brain.
CC {ECO:0000269|PubMed:10095018}.
CC -!- DOMAIN: Transport is mediated via a series of conformation changes,
CC switching between a conformation where the substrate-binding cavity is
CC accessible from the outside, and a another conformation where it is
CC accessible from the cytoplasm. {ECO:0000250|UniProtKB:P11169}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily. Sugar
CC transporter (TC 2.A.1.1) family. Glucose transporter subfamily.
CC {ECO:0000305}.
