The work in our Lab is focused on advancing molecular mechanisms for the function and regulation of plasma membrane metal transporters. These transporters play fundamental roles in regulating cellular metabolism and cellular function. Mutations and malfunctioning of these transporters are directly pertinent to the initiation and the progression of an increasing number of human diseases, including iron deficiency, hemochromatosis, cancer, and childhood on-set neurodegeneration. We identify and characterize the genes and factors that are involved in determining the structure and function of these metal transporters. We also examine the intracellular trafficking and degradation of these proteins.
