General annotation (Comments)

Function	Probably involved in copper transport and in the regulation of cellular copper level. Retrieves copper from the metallochaperone ATX1 and incorporates it into trans-Golgi vesicles.
Catalytic activity	ATP + H(2)O + Cu(2+)(In) = ADP + phosphate + Cu(2+)(Out).
Subcellular location	Golgi apparatus › trans-Golgi network membrane; Multi-pass membrane protein.
Sequence similarities	Belongs to the cation transport ATPase (P-type) family. Type IB subfamily. Contains 2 HMA domains.
