Recombinant proteins for solute carrier family 19 member 3 are available from various sources. In humans, this protein has a Uniprot ID of Q9BZV2 and has an annotated function: 'Mediates high affinity thiamine uptake, probably via a proton anti-port mechanism.' This protein is 496 amino acids in length and 55.7 kilodaltons in mass. This protein is encoded by the gene SLC19A3. Other names also exist, such as: thiamine transporter 2, solute carrier family 19 (thiamine transporter), member 3, thTr-2. This protein is conserved in other species, including: mouse, rat.
