SLCO1B3 Mediates the Na(+)-independent uptake of organic anions such as 17-beta-glucuronosyl estradiol, taurocholate, triiodothyronine (T3), leukotriene C4, dehydroepiandrosterone sulfate (DHEAS), methotrexate and sulfobromophthalein (BSP).Involved in the clearance of bile acids and organic anions from the liver. Defects in SLCO1B3 are a cause of hyperbilirubinemia, Rotor type (HBLRR). An autosomal recessive form of primary conjugated hyperbilirubinemia. Affected individuals develop mild jaundice not associated with hemolysis shortly after birth or in childhood. They have delayed plasma clearance of the unconjugated anionic dye bromsulphthalein and prominent urinary excretion of coproporphyrin I. Hepatic pigmentation is normal. Belongs to the organo anion transporter (TC 2.A.60) family. Note: This description may include information from UniProtKB.
