The Cell Biology of the Menkes Disease Protein
Copper is a trace element which is readily converted between cuprous and cupric forms under physiological conditions. This redox property has been harnessed in biological systems where copper forms an integral component of enzymes whose catalytic function involves electron exchange. However, this same property of copper also makes it toxic when present within the cell at elevated levels. Consequently, intracellular copper levels must be carefully controlled, presumably by regulated transport mechanisms. Disruptions of some of these mechanisms can have a genetic basis as illustrated in the case of both Menkes disease and Wilson disease (Danks, 1995).
