Research Focus

The overall research interest of the laboratory is to understand the role of ATP binding cassette (ABC) transporters in Biology and Medicine. These proteins, found in all species, use the energy of ATP hydrolysis to translocate specific substrates across cell membranes. Most of these transporters play important roles in normal biology and in the therapeutic response to medications.

Our current studies focus on 1) Identifying the physiological function, regulation and clinical significance of ABC transporters and 2) Understanding the significance of protein-protein interactions to the intracellular trafficking and functional activity of these multi domain transport machineries. We explore these questions through molecular and cellular biology, protein biochemistry and genetics. We complement our cell culture studies with whole animal studies to put our finding at the cellular level in the context of the whole animal. We expect that these studies will not only provide insight into the cellular role of these transporters but also help us translate this knowledge into new diagnostic and treatment strategies to optimize therapy.
