ABCC4 (Multidrug Resistance-associated Protein 4, ATP-binding Cassette Sub-family C Member 4, MRP/cMOAT-related ABC transporter, Multi-specific Organic Anion Transporter B, MOAT-B, ABCC4)

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. The specific function of this protein has not yet been determined; however, this protein may play a role in cellular detoxification as a pump for its substrate, organic anions. Alternative splicing results in multiple...
