Abstract
The copper-transporting ATPase ATP7B (Wilson ATPase) is a large trans-membrane protein with a complex multidomain architecture. ATP7B uses the subset of these domains to hydrolyze adenosine triphosphate (ATP) and to couple ATP hydrolysis with the transport of copper across the cell membranes. These activities are central to main physiological functions of ATP7B: the maintenance of copper homeostasis and synthesis of active ceruloplasmin. The other domains of ATP7B are used for regulation: using these structural elements, ATP7B responds to changing copper concentration in the cytoplasm and other signaling events. In this review, we summarize the available structural information on ATP7B and relate, whenever possible, the structural features of ATP7B to its function and regulation.
