Recombinant proteins for solute carrier family 22 member 11 are available from various sources. In humans, this protein has a Uniprot ID of Q9NSA0 and has an annotated function: 'Mediates saturable uptake of estrone sulfate, dehydroepiandrosterone sulfate and related compounds.' This protein is 550 amino acids in length and 60 kilodaltons in mass. It has been designated a subcellular localization as: cell membrane. This protein is encoded by the gene SLC22A11. Other names also exist, such as: solute carrier family 22 member 11, organic anion transporter 4, solute carrier family 22 (organic anion/cation transporter), member 11, solute carrier family 22 (organic anion/urate transporter), member 11. As many as 2 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
