Exploring How a Cell Consumes Itself

The ability to capture and degrade specific cytoplasmic targets including protein aggregates, invading pathogens or even whole dysfunctional organelles forms the basis of the cell's response to disease ranging from neurodegeneration to cancer and heart disease. In each case, large cytoplasmic targets are identified and encapsulated in a newly-formed organelle, the autophagosome, which wraps portions of cytosol in a double-membraned compartment and eventually delivers it to the lysosome for degradation. How these targets are identified and how this organelle forms are the major foci of our laboratory.

Recent Highlights

How autophagy proteins determine the unique structure of the autophagosome is just beginning to be understood. Our first efforts to study how the strident curvature present at the expanding rim of the growing phagophore might influence local biochemistry have just been published:
