    FAMILY
  • SLC21A superfamily of solute carriers
  • organo anion transporter family
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     plasma membrane
    text expressed on the sinusoidal membrane of human hepatocytes
    basic FUNCTION
  • transport of conjugated steroids (17beta glucoronosyl estradid, 3(H) estrone-3-sulfate, eicosanoids and thyroid hormones)
  • transporter of exogenous substance : bromosulfphophtalein, and predominantly involved in hepatic uptake of pravastatin
  • playing a role in prevention of hyperbilirubinemia by facilitating entry of unconjugated bilirubin in hepatocytes
  • involved in the hepatocellular uptake of a variety of endogenous and xenobiotic substances and drugs
  • plays an important role in the hepatic uptake of bile acids
  • plays a role in the pharmacokinetics of olmesartan, and the co-administration of olmesartan does not affect the pharmacokinetics of pravastatin or its metabolite
  • genetically polymorphic influx transporter which mediates the hepatic uptake of many endogenous compounds and xenobiotics
  • plays a major role in the hepatic uptake of drugs

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interaction of porphyrins with SLCO1B1, and tetrapyrroles are transported by SLCO1B1

    REGULATION

    ASSOCIATED DISORDERS
    corresponding disease(s)
    Susceptibility
  • to interindividual variability in the pharmacokinetics of olmesartan
  • to risk of statin-induced myopathy
  • Variant & Polymorphism other
  • polymorphism L193R, mutant protein SLC21A6-L193R was retained intracellularly, and this single amino acid exchange abolished transport function
  • polymorphism could contribute to the interindividual variability in the pharmacokinetics of olmesartan
  • common variants are strongly associated with an increased risk of statin-induced myopathy
  • Candidate gene
