Positive-strand RNA ((+)RNA) viruses such as SARS and MERS coronaviruses, Dengue, Zika and Hepatitis C viruses have devastating human health and socio-economic consequences. Upon infection (+)RNA viruses reorganize the intracellular host membranes to form replication complexes (RCs) to support viral genome replication. In the Ahlquist lab, I work with a highly advanced Nodavirus model system to study RC assembly, structure and function via a combination of cryo-electron microscopy and biochemical techniques. A detailed molecular understanding of viral RCs is essential to find novel drug targets to inhibit the replication and spread of (+)RNA viruses.
