How do protein quality control mechanisms maintain neuronal ageing? This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing.

This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misfolded proteins during ageing, within the nervous system of a living animal. Expected outcomes of this project will generate new knowledge of brain physiology and ageing relevant to all animals. This should provide significant benefits, such as a greater understanding of long-term brain functions including memory.Read moreRead less
Imaging Mass Spectrometry (IMS), a peptide biomarker discovery tool using tissue. Cancer is the second most common cause of death in Australia. The newly developed technology of Imaging Mass Spectrometry for peptides in tissue has the potential to discover biomarkers for early diagnosis of cancer. This new technology could avoid a number of cancer deaths and reduce suffering of patients through earlier and better diagnosis.
Disruptive approaches to biological sensing. Optical fibre-based biosensors have the potential to transform our ability to monitor our environment, protect our nation's assets and safeguard our citizens, and to offer improved clinical diagnostics and food quality control by creating tools that can detect biomolecules in real-time within complex samples.

Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins.

This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innovative genome editing, mathematical modelling and proteomic approaches, to study how biochemical modifications of a key protein called tau help encode and retrieve memories. These molecular insights will make a significant advance in the current understanding of a brain function that is essential to all human activities.Read moreRead less

The molecular interactome and functions of circular RNAs. This project aims to identify the functions of circular RNAs, the most contemporary and enigmatic family of RNA molecules. While their abundance suggests they are important, it is unclear how they function at the molecular level. This project aims to delineate circular RNA function by systematically identifying their interacting partners at the DNA, RNA and protein levels, the so-called molecular interactome. This project will reprogram e ....The molecular interactome and functions of circular RNAs.

While their abundance suggests they are important, it is unclear how they function at the molecular level. This project aims to delineate circular RNA function by systematically identifying their interacting partners at the DNA, RNA and protein levels, the so-called molecular interactome. This project will reprogram embryonic stem cells to model developmental processes and is designed to validate circular RNA research. Together, the benefits include a higher-quality research workforce by mentoring students, refining fundamental tenets of RNA biology and may extend to improving health in the long-term.Read moreRead less

Summary
Characterisation of collagenous lectins and their roles in ovine infectious diseases. Specific proteins involved in immunity against infections will be studied in sheep to enhance their immune response against specific infections, such as ovine Johne's disease and footrot. This may lead to selective breeding of sheep that are more resistant to disease, minimising production losses and use of medications.
Applications-oriented elucidation of germination triggers for Emu Bush seed. The project aims to determine the environmental and genetic mechanisms that currently limit seed germination in Emu Bush (Eremophila) species. The anticipated project outcomes aim to develop new technologies for efficient and mass production of Emu Bush seedlings. The outcomes will improve land restoration by increasing plant diversity and reducing establishment costs, and will also provide the nursery industry with nov ....Applications-oriented elucidation of germination triggers for Emu Bush seed.

The anticipated project outcomes aim to develop new technologies for efficient and mass production of Emu Bush seedlings. The outcomes will improve land restoration by increasing plant diversity and reducing establishment costs, and will also provide the nursery industry with novel products for home gardens. The intended project benefits are to increase the diversity of Australian native plants used for restoration and ornamental purposes and to promote the conservation of species in this plant family and its genetic diversity.Read moreRead less
Bacterial poly-histidine triad proteins. The poly-histidine triad (Pht) proteins are a poorly characterised family of surface proteins expressed by the genus Streptococcus and other Gram-positive genera. Recent studies suggest an important role for Pht proteins in survival of these bacteria in low zinc (Zn) environments. The project hypothesis is that Pht proteins specifically recruit Zn from the extracellular environment and somehow make it available to ATP binding cassette (ABC) transport syst ....Bacterial poly-histidine triad proteins. The poly-histidine triad (Pht) proteins are a poorly characterised family of surface proteins expressed by the genus Streptococcus and other Gram-positive genera. Recent studies suggest an important role for Pht proteins in survival of these bacteria in low zinc (Zn) environments. The project hypothesis is that Pht proteins specifically recruit Zn from the extracellular environment and somehow make it available to ATP binding cassette (ABC) transport systems located in the bacterial plasma membrane, beneath the cell wall, facilitating Zn uptake by the bacterium. The aim of this project is to conduct comprehensive molecular characterization of the interactions between Pht proteins, Zn and ABC transporters, and the role of the histidine triad motifs in these interactions.Read moreRead less

This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity. Metal ions are essential to all forms of life, and half of all proteins use metal ions for cellular chemical processes. However, how cells precisely balance sufficient metal ions for essential cellular chemistry without accumulating a toxic excess (metal homeostasis) is poorly understood. Discovering the roles of metal ions in bacterial cells will be key to defining the chemical biology of living systems and will provide information essential to understanding how microbes adapt to changing environments.Read moreRead less
