Protein attributes
| Sequence length | 1505 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Evidence at transcript level. |
General annotation (Comments)
| Function | Involved in the export of copper out of the cells, such as the efflux of hepatic copper into the bile By similarity. |
| Catalytic activity | ATP + H2O + Cu2+(In) = ADP + phosphate + Cu2+(Out). |
| Subunit structure | Monomer. Interacts with COMMD1/MURR1 By similarity. |
| Subcellular location | Golgi apparatus › trans-Golgi network membrane; Multi-pass membrane protein By similarity. Note: Predominantly found in the trans-Golgi network (TGN). Not redistributed to the plasma membrane in response to elevated copper levels By similarity. |
| Tissue specificity | The short isoform is expressed primarily in the liver with lower levels present in the intestine, hypothalamus and ovary. The long isoform is expressed in the liver. |
| Sequence similarities | Belongs to the cation transport ATPase (P-type) family. Type IB subfamily. Contains 6 HMA domains. |
