Decision-making modules in protein interaction networks. This project aims to discover how cells use proteins to make decisions. This is important for all living things, which must react to stimuli to grow, adapt, defend themselves and to die. The project’s anticipated outcome is the systems-level identification of decision-making modules in an intracellular network. Its focus is on the smallest possible modules, which contain a decision-making protein with two modifications that control protein ....Decision-making modules in protein interaction networks. This project aims to discover how cells use proteins to make decisions. This is important for all living things, which must react to stimuli to grow, adapt, defend themselves and to die. The project’s anticipated outcome is the systems-level identification of decision-making modules in an intracellular network. Its focus is on the smallest possible modules, which contain a decision-making protein with two modifications that control protein-proteins interactions. It will investigate two recurrent decision-making modules. The expected benefits of the project include new means to decipher biological complexity, and targets to modulate biosystems by genome editing or with drugs.Read moreRead less
The role and regulation of protein methylation: a study using the recently developed methylation network of yeast. Tiny changes to proteins, such as methylation, can alter the way they interact with other proteins. This project will investigate the dynamics of protein methylation during the life of the yeast cell. The project results will be of long term relevance to situations where we may want to stop cells dividing, such as cancer or infectious disease.
Does phosphorylation regulate the methylation of proteins? . The interaction of proteins is a fundamental requirement of life. Tiny switches on proteins affect how they interact but little is known about how these are controlled. This project will study the complex interplay between two types of switches; one is expected to control the other. This will provide new insights into how the cell functions.
The tau interactome. This project aims to decipher tau-dependent mechanisms at the molecular level to understand its pivotal role in neuronal integrity and function. Tau is a predominantly axonal protein with microtubule stabilising properties and has been implicated in several neurodegenerative disorders, including Alzheimer’s disease. Knowledge of its other physiological roles in the brain is limited, although it seems to be involved in signalling processes. The expected outcome of this study ....The tau interactome.

Tau is a predominantly axonal protein with microtubule stabilising properties and has been implicated in several neurodegenerative disorders, including Alzheimer’s disease. Knowledge of its other physiological roles in the brain is limited, although it seems to be involved in signalling processes. The expected outcome of this study is a deeper understanding of brain function during development and aging, which may ultimately contribute to new preventive treatments and medical care strategies.Read moreRead less
The role of N-linked protein glycosylation in Campylobacter jejuni. It is estimated that 300,000 Campylobacter jejuni (C. jejuni) infections occur in Australia annually, causing a vast economic loss. This project will assist in the understanding of the role of glycosylation and will significantly aid in determining how C. jejuni colonises humans and poultry and lead to the discovery of interventions to reduce the organism in poultry for human consumption.
The Regulatory Network of Histone Methylating and Demethylating Enzymes. This project aims to discover how cells regulate histone methylation enzymes. This process ultimately affects which genes can be turned on or off inside cells; something which is central to growth and development in all animals, all plants and some microbes. Expected outcomes include new knowledge on the regulation of histone methylation, improved techniques for the study of this process and enhanced capacity for internatio ....The Regulatory Network of Histone Methylating and Demethylating Enzymes. This project aims to discover how cells regulate histone methylation enzymes. This process ultimately affects which genes can be turned on or off inside cells; something which is central to growth and development in all animals, all plants and some microbes. Expected outcomes include new knowledge on the regulation of histone methylation, improved techniques for the study of this process and enhanced capacity for international collaboration. New avenues for the artificial regulation of genes may also emerge for synthetic epigenetics. The project should provide significant new findings for the research community, generate research citations and contribute to a highly skilled workforce by the training of staff and students.

Sugars in the real world: are cultured cancer cells a good model system for studying protein glycosylation? It is challenging to study errors in metabolism in human beings, so researchers use cells grown in the laboratory to understand disease processes. This project will determine if cultured cells accurately reflect the real changes to cell surface sugars that occur in all cancers, and the effect of these changes on the invasive properties of colon cancer cells.
Profiling tissue protein, elemental ions and nanoparticle distributions. This project aims to investigate protein-protein interactions that are crucial to homeostatic cell signalling and viability in a changing tissue environment. The central goal is to develop and validate protocols to combine cutting-edge tissue imaging modalities to map and characterise tissue distributions of native and modified proteins, elemental ions and pharmacological agents including nanoparticles and nanovehicles.

This project aims to investigate protein-protein interactions that are crucial to homeostatic cell signalling and viability in a changing tissue environment. The central goal is to develop and validate protocols to combine cutting-edge tissue imaging modalities to map and characterise tissue distributions of native and modified proteins, elemental ions and pharmacological agents including nanoparticles and nanovehicles. The aim is to use novel tissue scanning mass spectrometry techniques in conjunction with X-ray-based microprobe spectroscopy and advanced multi-parameter cytometry to identify spatial distributions of proteins, ions and drugs in tissues. This approach may provide new information about the maintenance of homeostatic control and the content, distribution and potential metabolism of drugs or nanoparticles within biological tissues.Read moreRead less
Mechanisms of gene regulation. This project aims to determine the molecular basis of specific gene targeting. Transcription factor complexes regulate gene expression by binding to DNA at specific sites, modifying and looping chromatin, and recruiting the basal transcription machinery. Using blood cell transcription factor complexes as a model, this project will reveal interactions between sets of proteins that fine-tune DNA binding and recruit accessory proteins that regulate gene expression.
