    text
  • basolateral membrane
  • expressed in the luminal membrane of human blood-brain barrier (BBB)
  • basic FUNCTION
  • involved in the transport of thyroid hormones,taurocholic acid and pravastatin (hepatic uptake of the liver-specific hydroxymethyl-glutaryl CoA reductase inhibitor)
  • role in the cellular uptake of All-trans-retinol (atROL), which might be essential to the proper functioning of the canonical visual cycle
  • membrane transporter that mediate the transport of wide ranges of compounds
  • membrane protein that mediate the cellular uptake of drugs and endogenous substances
  • role for AMPK in regulating OATP1A2 protein stability

    small molecule
    protein
  • protein kinase C regulates the transport function of OATP1A2 by modulating protein internalization
  • anti-migraine triptans are substrates for SLCO1A2, a transporter expressed at human blood-brain barrier
  • PDZK1 and SLC9A3R1 regulate the transport function of SLCO1A2 by modulating protein internalization via a clathrin-dependent pathway and by enhancing protein stability
  • transports VPA across the blood-brain barrier (BBB), suggesting altered SLCO1A2 expression may contribute to resistance to valproic acid (VPA) in patients with drug-resistant epilepsy
