Listed are ELISA Kits for the detection of OATP4A1, an alias name of solute carrier organic anion transporter family member 4A1. The human protein, encoded by the gene SLCO4A1, is 722 amino acid residues long and has a mass of 77,193 daltons. However, there are up to 4 reported isoforms. It is a member of the Organo anion transporter (TC 2.A.60) family. This protein is reported to have a membrane cellular localization, and is glycosylated. This target may also be known as: colon organic anion transporter, organic anion transporter polypeptide-related protein 1, organic anion transporting polypeptide E, solute carrier family 21 (organic anion transporter) member 12, and solute carrier family 21 member 12.
