Rouiller laboratory: Understanding how molecular machines function through cryo-electron microscopy
+61 3 9035 4902
The Rouiller lab utilises cryo-electron microscopy as a structural biology approach to study how molecular machines function. Using the single particle and tomography techniques, we determine the structures of molecular machines "in action" along their biological pathways. The systems we study include:
- The AAA ATPase p97 activity in health and disease: p97 is an essential protein for cell homeostasis that plays a major role in multiple cellular functions, including membrane. Our studies aim at understanding how p97 perform its functions at the molecular level in order to develop inhibitors to be used for the treatment of cancer and multisystem proteinopathy (e.g. Inclusion Body Myopathy with early-onset Paget disease and Frontotemporal Dementia- IBMFD and Amyotrophic Lateral Sclerosis- ALS).
- Transporters: We are studying the molecular mechanism that drive transport of substrates, proteins and ions across membranes. The systems we are studying include Anthrax toxins, ABC transporters (e.g. the MalFGK2 transporter), RND transporters (e.g. the mycolic acid transport from Mycobacterium tuberculosis) and ion transporters (e.g. the mechanosensitive ion channel TACAN).
- Viral glycoproteins (e.g. Influenza Hemagglutinin) involved in host pathogen interactions. We are interested in the structural implication these proteins for vaccine development and immune response.
