The long-term goal of this project is to determine the structure and function of this important ABC transport system and to understand the mechanism by which this ABC transporter translocates sterols across membranes. The project in the current phase is focusing on the role of intestinal expressed ABCG5/ABCG8 and the high-resolution structure of it. The Structure and Function of Mammalian V-type proton Translocation ATPases. The long-term goal of this project is to determine the structural basis of the function and regulation of V-type proton pumps. The project characterizes the catalytic center and a regulatory component of the V-type proton pump of clathrin-coated vesicles and studies the isoform structure of the major subunits in its membrane domain to determine the structural basis for the regulation of this pump Lipid asymmetry in plasma membrane and Apoptosis-induced PS exposure The long-term goal of this project is to elucidate the mechanism by which the maintenance of lipid asymmetry in plasma membrane and PS exposure during apoptosis are regulated.
