RESEARCH DESCRIPTION
Our laboratory is interested in the molecular characterization of the mechanism of Ca2+ transport by a group of ATPases associated with intracellular membranes, and the effects of these ATPases in cellular functions. These ATPases play an important role in control of the cytosolic Ca2+ concentration and, thereby, in regulation of cellular functions by Ca2+. Our experimental approach includes isolation of intracellular membranes; purification of proteins; kinetic measurements of ion fluxes and coupled enzyme reactions; studies of protein structure and function by chemical derivatization and site directed mutagenesis; gene transfer to express recombinant protein and to influence cellular functions.
