Summary

ABCC5 (ATP binding cassette subfamily C member 5, HGNC:56) is a protein-coding gene on chromosome 3q27.1, encoding ATP-binding cassette sub-family C member 5 (O15440). ATP-dependent transporter of the ATP-binding cassette (ABC) family that actively extrudes physiological compounds, and xenobiotics from cells.

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 analogs in HIV-infected patients. Alternative splicing results in multiple transcript variants.

Function. ATP-dependent transporter of the ATP-binding cassette (ABC) family that actively extrudes physiological compounds, and xenobiotics from cells. Mediates ATP-dependent transport of endogenous metabolites such as cAMP and cGMP, folic acid and N-lactoyl-amino acids (in vitro). Also acts as a general glutamate conjugate and analog transporter that can limit the brain levels of endogenous metabolites, drugs, and toxins. Confers resistance to the antiviral agent PMEA. Able to transport several anticancer drugs including methotrexate, and nucleotide analogs in vitro, however it does with low affinity, thus the exact role of ABCC5 in mediating resistance still needs to be elucidated. Acts as a heme transporter required for the translocation of cytosolic heme to the secretory pathway. May play a role in energy metabolism by regulating the glucagon-like peptide 1 (GLP-1) secretion from enteroendocrine cells.

Subcellular location. Basolateral cell membrane. Golgi apparatus lumen. Endosome membrane. Cytoplasmic granule. Apical cell membrane.

Tissue specificity. Predominant isoform in retinal pigment epithelium, bladder, and stomach. Ubiquitously expressed, but levels in brain and muscle are especially high. All isoforms are equally expressed in retina.

Activity regulation. cGMP transport is highly sensitive to inhibitors of cGMP phosphodiesterase, such as zaprinast, trequinsin and sildenafil.

Miscellaneous. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. Although other labs have confirmed the ability of ABCC5 to transport cGMP in an ATP-dependent manner, they obtained a much lower affinity for this substrate. The authors conclude that ABCC5 is a low-affinity cyclic nucleotide transporter a major function in cGMP excretion is unlikely.

Similarity. Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
