Anti-OATP4C1 antibodies enable researchers to detect and measure the OATP4C1 antigen in biological samples. This target is a reported synonym of the SLCO4C1 gene, which encodes solute carrier organic anion transporter family member 4C1. This protein is known to function in cell differentiation and the transport of ions, among other biological roles. The human version of OATP4C1 has a canonical amino acid length of 724 residues and a protein mass of 78.9 kilodaltons. It is reported to be localized in the cell membrane of cells. OATP4C1 is a member of the Organo anion transporter (TC 2.A.60) protein family.
