John Poulton’s research seeks to identify and characterize genes involved in normal kidney development, particularly those that, when mutated, either directly cause or predispose individuals to kidney disease. Dr. Poulton’s research program leverages the powerful genetic tools available in model organisms to study genes important for kidney function. His primary focus are genes that encode the numerous actin regulators and cell-cell junctional proteins present in podocytes, particularly those affecting slit diaphragm function. To understand the underlying cellular defects leading to kidney disease, we need to define the mechanism of action of these proteins, and how they work together or antagonistically in the cell. We also need to identify partner proteins with which they interact to perform their cellular function. Answering these questions can help us understand the etiology of the relevant diseases and identify new therapeutic targets.
