Facilitative glucose transporter (, ). 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 (, ). Required for mesendoderm differentiation (By similarity).
Subcellular locations: Cell membrane, Perikaryon, Cell projection
Localized to densely spaced patches along neuronal processes.
Highly expressed in brain . Expressed in many tissues.
