Recombinant proteins for solute carrier family 19 member 1 are available from various sources. In humans, this protein has a Uniprot ID of P41440 and has an annotated function: 'Transporter for the intake of folate.' This protein is 591 amino acids in length and 64.9 kilodaltons in mass. This protein is encoded by the gene SLC19A1. Other names also exist, such as: folate transporter 1, IFC-1, RFC, intestinal folate carrier 1, placental folate transporter, reduced folate carrier 1, reduced folate carrier protein, solute carrier family 19 (folate transporter), member 1. As many as 3 isoforms have been named. This protein is conserved in other species, including: mouse, rat, zebrafish, chimpanzee, guinea pig.
