A genomic fragment (Pacman clone CH3222-77E05) containing the entire ATP7 gene, which has been mutated to contain the amino acid replacement K552R. This mutation is equivalent to the disease-associated K832R mutation in the orthologous human ATP7A gene (associated with susceptibility to Alzheimer's disease). A EGFP tag has been inserted at the C-terminal end of the ATP7 open reading frame.
