Brief description Copper is an element that is essential for life but is highly toxic in excess. Because of this, the regulation of copper uptake, distribution in the body and excretion of excess is a very tightly regulated process. Until recently little was known about the molecular basis of this process. Two genetic disorders that show these two aspects of copper are Menkes disease (deficiency) and Wilson disease (toxicity). Both diseases are caused by mutations in similar copper pumping proteins. Our research is trying to establish the molecular mechanisms used in the body to control copper metabolism. We made a major breakthrough in 1993 with the isolation of the gene affected in Menkes disease, and we continue to be one of the leading groups in the world in studying the molecular mechanisms that handle copper, and the importance of these mechanisms in health and disease. Research into the biology of copper has become much more important following the recent discoveries of the involvement of the metal in such important neurodegenerative conditions such as Alzheimer's, Mad Cow, and Parkinson's diseases. Health effects from the lack of copper may be widespread also, copper deficiency is suspected to contribute to some common diseases, such as cardiovascular problems and osteoporosis. Our research is providing information about copper transport mechanisms that are necessary for the understanding of, and may lead to better treatment and diagnosis of common and important diseases. In this grant we propose to continue our studies into the molecular signals that control the copper pumps, that make the regulation of copper metabolism possible. We also will use various test systems for studying the effect of mutations on the activity of these proteins and relate these effects to the type of disease produced in patients.
