Protein attributes
| Sequence length | 883 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Mediates copper transfer across the chloroplast thylakoid membrane. Required for copper delivery into the thylakoids lumen, which is essential for the function of copper proteins. Ref.1 |
| Catalytic activity | ATP + H2O + Cu2+(In) = ADP + phosphate + Cu2+(Out). |
| Subcellular location | Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein Ref.1. |
| Tissue specificity | Expressed in the shoots only and not in the roots. Ref.1 |
| Disruption phenotype | High-chlorophyll-fluorescence phenotype. Ref.1 |
| Sequence similarities | Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily. [View classification] Contains 1 HMA domain. |
| Sequence caution | The sequence AAO73891.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAC34486.1 differs from that shown. Reason: Erroneous gene model prediction. |
