Multidrug resistance protein 3 is a protein that in humans is encoded by the ABCB4 gene. ABCB4 is associated with progressive familial intrahepatic cholestasis type 3.The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1 MDR/TAP MRP ALD OABP GCN20 White).
