Copper-transporting ATPases convey copper ions across cell-surface and intracellular membranes. They consist of eight TM domains and associate with multiple copper chaperone proteins (e.g. ATOX1, O00244).

Ensembl ID ENSG00000123191 (Hs), ENSMUSG00000006567 (Mm), ENSRNOG00000012878 (Rn)
UniProtKB AC P35670 (Hs), Q64446 (Mm), Q64535 (Rn)
EC number
Comment Autosomal recessive genetic variants that decrease ATP7B function cause Wilson's disease. Symptoms arise due to excess copper accumulation and damage to organs including the liver, brain, kidneys, heart and eyes, as a direct result of inadequate ATP7B-mediated copper excretion into the biliary system.
