Biography

Janet Yang received her BS from Yale University and then promptly headed for the West Coast. She attended the University of California San Francisco for her PhD in Biochemistry, and then did her postdoctoral work at the California Institute of Technology. Prof. Yang has always been fascinated by molecular motor proteins that harness the energy from ATP binding and hydrolysis to perform work in the cell. Her research uses quantitative thermodynamic and kinetic measurements to understand how these motor proteins function and how they are regulated.

At USF, the Yang Group studies the mechanism of ATP Binding Cassette (ABC) transporters, specialized integral membrane proteins that regulate the movement of substrates across cellular membranes. These transporters must sequester and import essential nutrients with low availability, as well as identify and exclude toxic compounds. Using a variety of biochemical and biophysical techniques, studies focus on the coupling of ATP binding and hydrolysis to transport, the regulation of individual ABC transporters, and the interconnection between transporter systems within one cell.
