    Research Areas

    1. Mechanisms of free energy transduction in enzymes

    2. Active transport (Ca2+) in biomembranes

    3. Excitation-contraction coupling in skeletal and cardiac muscle

    4. Ca2+ and signal transduction

    5. Gene transfer in Eukaryotic cells
    Dr. Inesi's laboratory has been engaged in a long term research project on Molecular and Cellular Aspects of the Ca2+ Transport ATPase. This enzyme is a membrane bound protein that utilizes ATP for active transport of Ca2+, and is required for storage of Ca2+ in intracellular stores. In turn, release of the stored Ca2+ is required for intracellular signaling and initiation of most cellular functions as a second messenger. Dr Inesi's molecular studies include determination of enzyme and transport kinetics, protein chemistry and derivatization of various amino acid residues, and production of recombinant protein to obtain specific mutations and assess their effects on catalytic and transport function. More recently, Idr Inesi has become involved in studies of bacterial and mammalian copper ATPases obtained by high yield heterologous expression in cultured cells, yielding characterization of specific phosphorylation and trafficking patterns related to copper matabolism in human diseases. This research is currently supported by a National Institutes of Health (NIHLBI) award.
