Anti-OATP2A1 antibodies are protein reagents that detect specific antigens. The OATP2A1 antigen is another term for the human protein solute carrier organic anion transporter family member 2A1, encoded by the SLCO2A1 gene. The protein is known to mediate the transport of prostaglandins (PGs, mainly PGE2, PGE1, PGE3, PGF2alpha, PGD2, PGH2) and thromboxanes (thromboxane B2) across the cell membrane. Canonically, it has an amino acid length of 643 residues and a mass of 70 kilodaltons. Its subcellular localization is in the cell membrane, lysosomes and cytoplasm and it is ubiquitously expressed across many tissue types. The OATP2A1 protein is a member of the Organo anion transporter (TC 2.A.60) protein family. Other alias names for OATP2A1 include MATR1 and PGT.
