Background
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 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. This protein may be involved in resistance to thiopurines in acute lymphoblastic leukemia and antiretroviral nucleoside

Cellular localization
Basolateral cell membrane ; Multi-pass membrane protein . Golgi apparatus lumen . Endosome membrane . Cytoplasmic granule . Apical cell membrane ; Multi-pass membrane protein . In most cells, routes to the basolateral plasma membrane, but in the brain capillary endothelial cells that form the blood-brain barrier, resides in the apical membrane. .
Tissue expression
[Isoform 3]: Predominant isoform in retinal pigment epithelium, bladder, and stomach. ; Ubiquitously expressed, but levels in brain and muscle are especially high (PubMed:9827529, PubMed:10438534, PubMed:15501592). All isoforms are equally expressed in retina (PubMed:17521428).
