Multidrug resistance-associated protein 6 (MRP6) also known as ATP-binding cassette sub-family C member 6 (ABCC6) and multi-specific organic anion transporter E (MOAT-E) is a protein that in humans is encoded by the ABCC6 gene.[5][6][7] The protein encoded by the ABCC6 gene is a member of the superfamily of ATP-binding cassette (ABC) transporters.[5]

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 multidrug resistance.[8]

Pathology

Mutations in this protein cause pseudoxanthoma elasticum (PXE).[9] The most common mutations, R1141X and 23-29del, account for about 25% of the found mutations.[10][11]

Premature atherosclerosis is also associated with mutations in the ABCC6 gene, even in those without PXE.[12]

Deficiency of Abcc6 in mouse models of ischemia leads to larger infarcts, which can be rescued by Abcc6 overexpression.[13]

Location

Abcc6 gene encodes an intracellular transporter associated with mitochondrial function, located in the mitochondrial-associated membrane (MAM), whereas its substrate can be located in either MAM, cytosol or ER.[14] Abcc6 is primarily expressed in liver and kidney,.[15][16]
