Facilitative glucose transporter. This isoform may be responsible for constitutive or basal glucose uptake. Has a very broad substrate specificity; can transport a wide range of aldoses including both pentoses and hexoses.
Specificity
Natural and recombinant Human Solute carrier family 2, facilitated glucose transporter member 1
Subcellular Location
Cell membrane Multi-pass membrane protein Melanosome Localizes primarily at the cell surface (By similarity). Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
