Recombinant proteins for solute carrier family 2 member 5 are available from various sources. In humans, this protein has a Uniprot ID of P22732 and has an annotated function: 'Functions as a fructose transporter that has only low activity with other monosaccharides.' This protein is 501 amino acids in length and 55 kilodaltons in mass. It has been designated a subcellular localization as: cell membrane. This protein is encoded by the gene SLC2A5. Other names also exist, such as: solute carrier family 2, facilitated glucose transporter member 5, glucose transporter type 5, small intestine, glucose transporter-like protein 5, solute carrier family 2 (facilitated glucose/fructose transporter), member 5, testicular tissue protein Li 81. As many as 2 isoforms have been named. This protein is conserved in other species, including: mouse, rat, chimpanzee, guinea pig.
