To infect a eukaryotic cell, many types of viruses need to overcome the nuclear envelope that forms a barrier to macromolecular transport between the cell cytoplasm and the nucleus. To do so, they exploit the pathway provided by the nuclear pore complex, the main gate for all nucleocytoplasmic transport. In this project, we will use biophysical approaches to image and probe the nuclear pore complex to understand the mechanisms by which it achieves transport of large cargoes yet maintain selectivity.
