Recombinant proteins for solute carrier family 22 member 18 are available from various sources. In humans, this protein has a Uniprot ID of Q96BI1 and has an annotated function: 'May act as a transporter of organic cations based on a proton efflux antiport mechanism.' This protein is 424 amino acids in length and 44.9 kilodaltons in mass. It has been designated a subcellular localization as: cell membrane. This protein is encoded by the gene SLC22A18. Other names also exist, such as: solute carrier family 22 member 18, beckwith-Wiedemann syndrome chromosomal region 1 candidate gene A protein, efflux transporter-like protein, imprinted multi-membrane-spanning polyspecific transporter-related protein 1, organic cation transporter-like protein 2, p45 Beckwith-Wiedemann region 1A, tumor-suppressing STF cDNA 5 protein, tumor-suppressing subchromosomal transferable fragment candidate gene 5 protein. This protein is conserved in other species, including: mouse, rat, chimpanzee, guinea pig.
