ATP7B (WND) protein

Int J Biochem Cell Biol. 1998 Oct;30(10):1063-7. doi: 10.1016/s1357-2725(98)00073-9.

Abstract

Wilson's disease is a genetic disorder of copper metabolism characterized by the excessive accumulation of this metal in the liver. The gene for Wilson's disease, designated ATP7B, encodes a copper transporting P-type ATPase expressed predominantly in the liver. Over 60 disease specific mutations of ATP7B have now been reported in patients with Wilson's disease. The gene for ATP7B is approximately 80 kb and contains 21 exons that encode an approximately 7.5 kb transcript. Recent studies that focus on the structure and expression of the ATP7B protein support its role as a copper transporter involved in the intracellular trafficking of copper in hepatocytes. The introduction of functional ATP7B protein by recombinant adenovirus mediated gene delivery will be a potential approach for correcting Wilson's disease.
