I am interested in the basic questions of how proteins transport cations across cellular membranes: How is selectivity determined? What conformational rearrangements are necessary for translocation? How is transport activity regulated by cellular conditions? One line of research in my lab focuses on transporters that are located in intracellular organelles, in specific, calcium transporters of the vacuolar compartment of the budding yeast Saccharomyces cerevisiae. This process is particularly amenable for several reasons. First, it is a biologically important problem: intracellular calcium is vital in many cellular processes, and its concentration is tightly controlled by sequestration or release from a variety of intracellular organelles using ion channels or transporters. Second, these intracellular calcium transport proteins are well-suited for attack by classic biochemical and functional methods particularly appropriate for undergraduate researchers. We are starting by addressing very basic questions of membrane topology, with the ultimate goal of understanding the molecular basis of transport (including selectivity & stoichiometry), as well as how activity is regulated.
