The ATP7B gene encodes the Wilson disease p-type ATPase.
ATP7B gene encodes a polypeptide that acts as a membrane copper-transport protein. ATP7B protein is required for incorporation of copper into ceruloplasmin in the liver and for biliary excretion of copper. ATP7B may also be involved in the transport of copper to a vesicular compartment. Copper from these vesicles may be delivered to lysosomes.
