Selective enrichment of proteins using micro-Gradiflow technology and characterisation of proteins using LC-MS/MS. This project describes crucial areas for the technology development of protein enrichment and fractionation. While current techniques are powerful, the usefulness to identify and characterise proteins of low abundance from massively complex samples in the presence of abundant proteins is limited and requires up to mililitre volumes.

This project describes crucial areas for the technology development of protein enrichment and fractionation. While current techniques are powerful, the usefulness to identify and characterise proteins of low abundance from massively complex samples in the presence of abundant proteins is limited and requires up to mililitre volumes. We intend to develop the micro-Gradiflow technology in association with Gradipore as a means of protein fractionation using microlitre volumes of sample. This technology will be applicable to all areas of proteomic research and in particular to the study of cell differentiation. The outcome for Australian industry, our competitiveness both industrial and scientific, and the potential for economic advancement is tremendous.Read moreRead less
Improving the sustainability of Australia's water resources: an effective approach for diagnosing and treating foulants on water recycling membrane filters. By determining ways to diagnose and treat fouling problems we will have effectively solved a critical problem in the water recycling industry. By creating more efficient and sustainable ways of using water, we will transform the effectiveness of a wealth of Australian industries that increasingly rely on the efficient use of water (e.g. mini ....Improving the sustainability of Australia's water resources: an effective approach for diagnosing and treating foulants on water recycling membrane filters. By determining ways to diagnose and treat fouling problems we will have effectively solved a critical problem in the water recycling industry. By creating more efficient and sustainable ways of using water, we will transform the effectiveness of a wealth of Australian industries that increasingly rely on the efficient use of water (e.g. mining, agriculture, textiles, energy). By reducing the demand for water (by effectively recycling it), and the energy requirements (by efficiently recycling it), we will increase national wealth and provide significant social and environmental benefits to all Australians.Read moreRead less

Soft matter research touches every aspect of our lives as it covers materials from the range of plastics found in cars, television sets and other mass-manufactured products, to new medical materials for tissue engineering and sensors. The proposed facility will enable Australia's leading scientists in this area to understand better how soft matter, including both biological and new advanced soft materials, behaves on the nano-scale level. This will put Australian researchers and engineers in a leading position for developing new treatments against cancer and other diseases, as well as harnessing the power of biology for application in areas such as waste treatment and energy production.Read moreRead less
Subunit stoichiometry and arrangement in the glycine receptor. Glycine receptors are important for nervous system function. These receptors comprise a mixture of 5 alpha and beta subunits arranged around a central ion-conducting pore. The subunit stoichiometry (i.e., numbers of alpha and beta subunits) and arrangement (i.e., subunit order) are unknown. The first aim of this project is to define these parameters using tethered subunits. The second aim is to use the tethered subunits to probe th ....Subunit stoichiometry and arrangement in the glycine receptor. Glycine receptors are important for nervous system function. These receptors comprise a mixture of 5 alpha and beta subunits arranged around a central ion-conducting pore. The subunit stoichiometry (i.e., numbers of alpha and beta subunits) and arrangement (i.e., subunit order) are unknown. The first aim of this project is to define these parameters using tethered subunits. The second aim is to use the tethered subunits to probe the structure and function of glycine and zinc binding sites at an unprecedented level of resolution. The results will provide crucial new information concerning glycine receptor structure and function.Read moreRead less
Gating and permeation in ClC channels. Chloride ion channels are essential proteins in all living cells but, compared to other channels, little is known of their structure or how this defines and controls chloride transport. We will produce both normal and structurally modified (mutant and known to cause disease) chloride channels in cultured cells by genetic engineering so that we can analyse channel function using a combination of electrophysiological and chemical methods. We expect to learn ....Gating and permeation in ClC channels. Chloride ion channels are essential proteins in all living cells but, compared to other channels, little is known of their structure or how this defines and controls chloride transport. We will produce both normal and structurally modified (mutant and known to cause disease) chloride channels in cultured cells by genetic engineering so that we can analyse channel function using a combination of electrophysiological and chemical methods. We expect to learn which channel parts are fundamental and how subtle changes in structure can alter the opening and closing of these channels and the way that chloride passes through them.Read moreRead less
Conantokin selectivity for heteromeric N-methyl-D-aspartate (NMDA) receptors. NMDA receptors are ligand gated ion channels formed by heterogeneous population of subunits with distinct pharmacological and biophysical properties. The heterogeneic receptors are differentially expressed during development and play an important role in many physiological and pathological processes. Conantokins are toxins isolated from Conus venoms, which target NMDA receptor subunits with high affinity. The primary g ....Conantokin selectivity for heteromeric N-methyl-D-aspartate (NMDA) receptors.

The heterogeneic receptors are differentially expressed during development and play an important role in many physiological and pathological processes. Conantokins are toxins isolated from Conus venoms, which target NMDA receptor subunits with high affinity. The primary goal of this study is to examine the effects of conantokins on the molecular properties of different NMDA receptor subtypes in vivo and in vitro.Read moreRead less

The work proposed will provide quantum advances in our understanding of the molecular basis by which clusterin effects its protective actions. We expect to demonstrate that clusterin protects cells form stresses by exerting its chaperone action at or near the cell surface and to identify specific regions and structural features of the clusterine molecule important in its chaperone action.Read moreRead less

The Tasmanian Devil (Sarcophilus harrisii) is a carnivorous marsupial endemic to the island state of Tasmania, and is found all over the state. Over the past decade, a dramatic decline has occurred in the Devil population in association with the emergence of Devil Facial Tumour Disease (DFTD). This project aims to develop a preclinical diagnostic test for DFTD that will provide vital information for use in developing management strategies to ensure the ongoing survival of the Tasmanian Devil. The benefit to Australia in performing this research rests in the new technology that will be developed and the application of this technology to key areas of national and international significance.Read moreRead less
