Gene Name MRP2
Uniprot ID MRP2_HUMAN
KEGG Pathway hsa:1244
Protein Family ABC transporter superfamily
Protein Function
ATP-dependent transporter of the ATP-binding cassette (ABC) family that binds and hydrolyzes ATP to enable active transport of various substrates including many drugs, toxicants and endogenous compound across cell membranes. Transports a wide variety of conjugated organic anions such as sulfate-, glucuronide- and glutathione (GSH)-conjugates of endo- and xenobiotics substrates (PubMed:10220572, PubMed:10421658, PubMed:11500505, PubMed:16332456). Mediates hepatobiliary excretion of mono- and bis-glucuronidated bilirubin molecules and therefore play an important role in bilirubin detoxification (PubMed:10421658). Mediates also hepatobiliary excretion of others glucuronide conjugates such as 17beta-estradiol 17-glucosiduronic acid and leukotriene C4 (PubMed:11500505). Transports sulfated bile salt such as taurolithocholate sulfate (PubMed:16332456). Transport various anticancer drugs, such as anthracycline, vinca alkaloid and methotrexate and HIV-drugs such as protease inhibitors (PubMed:10220572, PubMed:11500505, PubMed:12441801). Confers resistance to several anti-cancer drugs including cisplatin, doxorubicin, epirubicin, methotrexate, etoposide and vincristine (PubMed:10220572, PubMed:11500505).

      Mechanism Description
  • Decreased clearance of Gadobenic acid and Paclitaxel (protein-bound) due to competitive inhibition of the same transporter

Recommended Action
      Management Caution is advised during concomitant use of gadobenate dimeglumine and other substrates of MRP2. Patients should be monitored for potentially increased pharmacologic effects of gadobenate dimeglumine as well as the coadministered drug(s).
