||ABCC5 (ATP Binding Cassette Subfamily C Member 5) is a Protein Coding gene. Diseases associated with ABCC5 include Lymphoblastic Leukemia. Among its related pathways are Glycosaminoglycan metabolism and CDK-mediated phosphorylation and removal of Cdc6. The protein encoded by ABCC5 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 functions in the cellular export of its substrate, cyclic nucleotides. This export contributes to the degradation of phosphodiesterases and possibly an elimination pathway for cyclic nucleotides. Studies show that this protein provides resistance to thiopurine anticancer drugs, 6-mercatopurine and thioguanine, and the anti-HIV drug 9-(2-phosphonylmethoxyethyl)adenine.
