ATP-binding cassette, sub-family C (CFTR/MRP), member 2, also known as ABCC2, is a human gene.cite web | title = Entrez Gene: ABCC2 ATP-binding cassette, sub-family C (CFTR/MRP), member 2| url =| accessdate = ]

summary_text = The 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). This protein is a member of the MRP subfamily, which is involved in multi-drug resistance. This protein is expressed in the canalicular (apical) part of the hepatocyte and functions in biliary transport. Substrates include anticancer drugs such as vinblastine; therefore, this protein appears to contribute to drug resistance in mammalian cells. Several different mutations in this gene have been observed in patients with Dubin-Johnson syndrome (DJS), an autosomal recessive disorder characterized by conjugated hyperbilirubinemia.cite web | title = Entrez Gene: ABCC2 ATP-binding cassette, sub-family C (CFTR/MRP), member 2| url =| accessdate = ]
