To understand how Hendra virus multiplies in infected cells, we will investigate the structure of its replicative machinery. This will provide the basis for rational drug design increasing Australia’s preparedness against the emergence of Hendra-like viruses.

Summary
Protein-RNA interactions play key roles in antiviral cellular defence and inflammation. Investigation of these molecular interactions will lead to new therapeutic targets and means of combating virus-related disease and inflammatory disorders.
The ins and outs of HIV biology. This project aims to delineate the fundamental mechanisms that regulate the production of HIV and the ability of HIV to cause AIDS in infected patients. It will utilise state-of-the-art technologies to unearth new clues that govern the biology of HIV, with the ultimate goal to develop novel vaccine and treatment strategies against HIV.

Summary
Smallpox is an ancient and dreadful disease that enormously influenced human history causing over 300 millions of deaths in the 20th century only. Human cases of monkeypox virus in the US and the potential use of smallpox as a bioterrorism weapon have called for an urgent improvement in Australia's preparedness against poxviruses. We investigate the assembly of these viruses to advance our fundamental understanding of poxvirus biology and provide rationally designed drugs to fight them off.
Uncovering mechanisms of protein multifunctionality. This project aims to use viral proteins to uncover fundamental mechanisms underlying protein multifunctionality, a central but poorly understood aspect of biology. This project expects to use multidisciplinary approaches to define novel and unexpected mechanisms by which single protein sequences can generate proteins with profoundly different structures and functions. Expected outcomes include a major shift in the understanding of protein fun ....Uncovering mechanisms of protein multifunctionality. This project aims to use viral proteins to uncover fundamental mechanisms underlying protein multifunctionality, a central but poorly understood aspect of biology. This project expects to use multidisciplinary approaches to define novel and unexpected mechanisms by which single protein sequences can generate proteins with profoundly different structures and functions. Expected outcomes include a major shift in the understanding of protein function in life, with most immediate impact in virology. This should provide significant benefits in identifying new strategies for treating viral infections, but also enhance developing multidisciplinary approaches to solve complex biological problems.Read moreRead less
Regulation of DNA synthesis and host evasion by Lentivirus Capsids. This project aims to investigate how a type of virus, exemplified by HIV, can synthesise DNA in the cytoplasm of a host cell, without triggering the cell’s innate immunity when DNA is detected outside the nucleus. It expects to advance understanding of the role of the virus’ protein shell in regulating DNA synthesis during infection. The project outcomes should include enhanced capacity for fundamental virus and cell biology re ....Regulation of DNA synthesis and host evasion by Lentivirus Capsids.

It expects to advance understanding of the role of the virus’ protein shell in regulating DNA synthesis during infection. The project outcomes should include enhanced capacity for fundamental virus and cell biology research in Australia. The project anticipates contributing to new tools for delivering genes to cells, benefiting therapeutic and biotechnology applications.Read moreRead less
Structural insights of virus-glycan interactions. Influenza virus, rotavirus and Dengue virus infect the body by adhering to certain types of sugars on the human cell surface. This project will develop a detailed structural understanding of how viruses interact with those sugar molecules for the development of novel drugs and vaccines to combat influenza and rotaviral infections.

Summary
Structural basis of paramyxovirus host cell entry. This project aims to investigate interactions between paramyxoviruses and host cell receptors and the mechanisms underlying fusion activation at a molecular level. Paramyxoviruses include economically important human and animal pathogens. Two viral proteins are key to infection: an attachment protein for the interaction with host receptors, and a fusion protein for fusion of viral and cellular membranes. The project is anticipated to discover ge ....Structural basis of paramyxovirus host cell entry. This project aims to investigate interactions between paramyxoviruses and host cell receptors and the mechanisms underlying fusion activation at a molecular level. Paramyxoviruses include economically important human and animal pathogens. Two viral proteins are key to infection: an attachment protein for the interaction with host receptors, and a fusion protein for fusion of viral and cellular membranes. The project is anticipated to discover general principles of how paramyxoviruses infect host cells, which should advance fundamental understanding of viral infection strategies and may identify strategies for rational design of inhibitors targeting host-cell entry of multiple paramyxoviruses.Read moreRead less

Characterisation of avian circovirus protein complexes. This project aims to better understand how the beak and feather disease virus (BFDV) is assembled. The virus affects Australian native birds, which are currently endangered or critically endangered and has the potential to disrupt native ecosystems.

The virus affects Australian native birds, which are currently endangered or critically endangered and has the potential to disrupt native ecosystems. By using interdisciplinary research, this project will generate fundamental knowledge by which BFDV protein complexes are formed. The intended outcomes of the project include the identification of key binding interfaces involved in viral formation processes. This information intends to guide cost-effective delivery of potential anti-viral options or vaccines for endangered Australian native parrots, and for use as a model to target other pathogenic DNA viruses of interest.Read moreRead less
In vivo assembly and virulence of poxvirus infectious crystals. Widespread insect viruses have evolved unique infectious forms called crystalline armours. This project will use innovative biophysical approaches to understand how these virus-containing crystals assemble and package viruses and contribute to virulence as a rational basis for improved bioinsecticides and novel microparticles for biotechnological applications.
