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+(Side 1) = ADP + phosphate + Cu2+(Side 2).

Subcellular location

Plastidchloroplast 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.

Alternative products

This entry describes 1 isoform produced by alternative splicing. [Select]

Note: A number of isoforms are produced. According to EST sequences.
Isoform 1 (identifier: B9DFX7-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
