Recombinant proteins for solute carrier family 2 member 4 are available from various sources. In humans, this protein has a Uniprot ID of P14672 and has an annotated function: 'Insulin-regulated facilitative glucose transporter.' This protein is 509 amino acids in length and 54.8 kilodaltons in mass. It has been designated a subcellular localization as: cytoplasmic, cell membrane. This protein is encoded by the gene SLC2A4. Other names also exist, such as: solute carrier family 2, facilitated glucose transporter member 4, GLUT-4, glucose transporter type 4, insulin-responsive, insulin-responsive glucose transporter type 4, solute carrier family 2 (facilitated glucose transporter), member 4. As many as 2 isoforms have been named. This protein is conserved in other species, including: mouse, rat, chimpanzee, guinea pig.
