A number of ELISA Kits are available that target Oatp4, an alias of the protein, solute carrier organic anion transporter family member 1B3. The human protein, encoded by the gene SLCO1B3, is a member of the Organo anion transporter (TC 2.A.60) family. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: HBLRR, LST-2, LST-3TM13, LST3, OATP-8, OATP1B3, OATP8, SLC21A8. Homology is conserved in other species, such as Mouse, Rat, Frog.
