Recombinant proteins for solute carrier family 22 member 3 are available from various sources. In humans, this protein has a Uniprot ID of O75751 and has an annotated function: 'Mediates potential-dependent transport of a variety of organic cations.' This protein is 556 amino acids in length and 61.3 kilodaltons in mass. This protein is encoded by the gene SLC22A3. Other names also exist, such as: solute carrier family 22 member 3, EMT organic cation transporter 3, extraneuronal monoamine transporter, organic cation transporter 3, solute carrier family 22 (extraneuronal monoamine transporter), member 3, solute carrier family 22 (organic cation transporter), member 3. This protein is conserved in other species, including: mouse, rat, zebrafish, chimpanzee.
