UniProtKB - Q5R608 (GTR3_PONAB)
Protein
Solute carrier family 2, facilitated glucose transporter member 3
Gene
SLC2A3
Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Functioni
Facilitative glucose transporter that can also mediate the uptake of various other monosaccharides across the cell membrane. Mediates the uptake of glucose, 2-deoxyglucose, galactose, mannose, xylose and fucose, and probably also dehydroascorbate. Does not mediate fructose transport.
