Recombinant proteins for solute carrier family 22 member 16 are available from various sources. In humans, this protein has a Uniprot ID of Q86VW1 and has an annotated function: 'High affinity carnitine transporter; the uptake is partially sodium-ion dependent.' This protein is 577 amino acids in length and 64.7 kilodaltons in mass. It has been designated a subcellular localization as: cell membrane. This protein is encoded by the gene SLC22A16. Other names also exist, such as: solute carrier family 22 member 16, WUGSC:RG331P03.1, carnitine transporter 2, epididymis secretory protein Li 18, flipt 2, fly-like putative organic ion transporter 2, fly-like putative transporter 2, organic cation transporter 6, organic cation transporter OKB1, organic cation/carnitine transporter 6, solute carrier family 22 (organic cation transporter), member 16, solute carrier family 22 (organic cation/carnitine transporter), member 16. As many as 3 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
