VIRUS BIOPHYSICS, DYNAMICS and STRUCTURE: Lee Lab (Membrane Fusion, Glycoprotein)

Viruses undergo dramatic structural reorganizations at many critical stages of their life cycles including during host cell invasion, membrane fusion, genome expulsion, assembly, and cell egress. The changes often involve concerted changes among hundreds of protein components and in the case of enveloped viruses, membranes as well. From this perspective, virions are intricate, nano-scale cell-invasion and replication machines. The dynamic structural transitions are attractive targets for anti-viral therapeutics that would jam the machinery and arrest viral infections.

We use biophysical, structural, and biochemical techniques including cryo-electron microscopy (cryoEM), small-angle X-ray scattering (SAXS), hydrogen/deuterium-exchange with mass spectrometry (HDX-MS), and fluorescence microscopy to understand the structure, dynamic responses and function of viral machinery.

The viruses we study primarily at this time are influenza A virus and HIV. In studies of influenza virus, we are focused on understanding the process of membrane fusion and fusion protein activation. In studies of HIV, we seek to understand the structural determinants of Env glycoprotein antigenicity and immunogenicity as a means of helping development of HIV vaccine immunogens.

The Lee lab is in the Department of Medicinal Chemistry, University of Washington. We are located in the H-wing of the UW Health Sciences Building. Interested students are encouraged to apply to our graduate program.

The lab is also a member of the Biological Physics, Structure & Design (BPSD), the Molecular & Cellular Biology (MCB) and the Pathobiology Graduate Programs.

Dr. Lee holds an adjunct appointment in the Microbiology Department. Students from the Microbiology Department are eligible to join the lab.
