Recombinant proteins for solute carrier family 22 member 12 are available from various sources. In humans, this protein has a Uniprot ID of Q96S37 and has an annotated function: 'Required for efficient urate re-absorption in the kidney.' This protein is 553 amino acids in length and 59.7 kilodaltons in mass. It has been designated a subcellular localization as: cell membrane. This protein is encoded by the gene SLC22A12. Other names also exist, such as: solute carrier family 22 member 12, organic anion transporter 4-like protein, renal-specific transporter, solute carrier family 22 (organic anion/cation transporter), member 12, solute carrier family 22 (organic anion/urate transporter), member 12, urate anion exchanger 1, urate transporter 1. As many as 4 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
