Current techniques for membrane protein are inadequate for the emerging proteomic challenge, in which approximately 40% of proteins are predicted to be membrane associated. The aim of this proposal is to develop a new approach to purify membrane proteins using our recently-developed immobilised membrane chromatography materials. The present proposal will provide a new high-resolution separation technique that allows isolation and on-line mass analysis of complex mixtures of membrane proteins for subsequent proteomic analysis, high-throughput screening or structural studies and could form the basis for further development of new commercial tools for membrane protein analysis.Read moreRead less
Differential Expression Proteomics: Identification and Quantitation of Peptides and Proteins by Fixed Charge Derivatization and Tandem Mass Spectrometry.

The aim of this proposal is to develop novel strategies for the rapid, sensitive and selective identification and quantitation of proteins present in complex mixtures. Specifically, isotopically labeled fixed charge derivatives of peptides containing selected amino acids will be developed that direct the formation of product ions following tandem mass spectrometry toward a single fragmentation channel. This approach will provide enhanced selectivity and sensitivity of up to 2 orders of magnitude over existing approaches, and will allow examination, at the protein level, of the complex cellular changes that occur following transformation of cells from a normal to a diseased state.Read moreRead less
Development of an ultrasensitive assay for human prion proteins. The aim of this work is to enable the detection of prion proteins in human blood and other tissues. The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and bl ....Development of an ultrasensitive assay for human prion proteins.

The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and blood products. Prions cause Bovine Spongiform Encaphalopathy and Creutzfeld Jacob Disease and attempts to control of these diseases would be greatly abetted by an optimal test for the disease-causing agent.Read moreRead less
Multiplexed bio-imaging mass spectrometry. This project aims to develop technology for simultaneous three-dimensional imaging of trace elements and molecules in biological tissues. This technology is an essential analytical and diagnostic advance to uncover latent mechanistic biology and will reveal subtle metabolic interactions between cells.

This project aims to develop technology for simultaneous three-dimensional imaging of trace elements and molecules in biological tissues. This technology is an essential analytical and diagnostic advance to uncover latent mechanistic biology and will reveal subtle metabolic interactions between cells. The project will use laser ablation-inductively coupled plasma-mass spectrometry and lanthanide-conjugated probes to map the zinc metabolic pathway in the ageing mouse brain. It is expected to result in a complete imaging solution for quantitative spatial determination of all important elements, co-factors, metabolites and other functional molecules to investigate metabolic pathways which current technologies find difficult or impossible to track. Ultimately this technology is expected to underpin investigations of diseases where trace metal and chemical species dysfunction is implicated.Read moreRead less

Training research scientists of the future forms an integral part of this research program and this collaboration will provide an excellent opportunity for young Australian scientists to be exposed to the very professional and competitive environment of basic research, as it exists in Germany. It will expose early career researchers to new ideas and emerging methodologies arming them with valuable skills, which they will transfer to Australia. The involvement of Prof. Turgay in the Deutsche Forschungsgemeinschaft (DFG) Priority Programme: Proteolysis in Prokaryotes also provides a unique opportunity for these young researchers to interact with several of the worlds leading scientists in the area of proteolysis, enhancing Australia's reputation at the forefront of science.Read moreRead less
Structural and functional studies of a Tripartite Motif-Containing Protein. This project will study a fundamental process that is crucial to the regulation of almost all cellular processes. The dysfunction of this process can lead to cancer, neurodegenerative and immunological disorders. The outcome will be an advancement in knowledgebase at the most fundamental level.
Unravelling transthyretin amyloid, bounding ahead using wallabies. Each protein in our body has a unique shape that enables it to function correctly. For unknown reasons, some proteins can change their shape, aggregate with other proteins and stick to the outside of cells of major organs or nerves. This prevents those cells from working properly and results in disease. Transthyretin is a protein that changes shape and aggregates in the heart of most people over the age of 70. The disease is call ....Unravelling transthyretin amyloid, bounding ahead using wallabies. Each protein in our body has a unique shape that enables it to function correctly. For unknown reasons, some proteins can change their shape, aggregate with other proteins and stick to the outside of cells of major organs or nerves. This prevents those cells from working properly and results in disease. Transthyretin is a protein that changes shape and aggregates in the heart of most people over the age of 70. The disease is called Senile Systemic Amyloidosis (SSA). It is not known how or why this happens. There is no cure or therapy. This project will use transthyretins from human and wallaby to explore a possible cause of SSA. If our hypothesis is correct, we will propose preventative actions to reduce the incidence of SSA in the future.Read moreRead less
Photodissociation mass spectrometry for lipidome analysis. This project aims to develop and apply novel bioanalytical mass spectrometry-based methods and workflows to illuminate the otherwise hidden structural diversity and molecular complexity of the lipidome.

This project aims to develop and apply novel bioanalytical mass spectrometry-based methods and workflows to illuminate the otherwise hidden structural diversity and molecular complexity of the lipidome. The structure of individual lipids define their specific biological functions. A major requirement of analytical methods employed for lipid analysis on a lipidome-wide scale, therefore, is to enable the detailed structural characterisation of the, potentially, tens of thousands of individual molecular lipid species that may be present within a sample of interest. This project will develop and optimise novel, ultraviolet photodissociation-tandem mass spectrometry methods which will be integrated within an automated lipidome analysis workflow, to enable comprehensive global lipidome profiling and to reveal the structural diversity of lipids involved in fundamental cellular signalling processes.Read moreRead less
