		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). Click to Show/Hide
Mechanism Description		Decreased clearance of Mycophenolic acid due to the transporter inhibition by Cyclosporine

Recommended Action
Management		Caution is advised when cyclosporine is used concomitantly with mycophenolate mofetil. Dosage adjustments as well as clinical and laboratory monitoring of MPA trough levels whenever cyclosporine is added to or discontinued from the patient's immunosuppressant regimen is recommended.
