Red Cell Polymorphisms and Malaria. Certain red blood cell disorders have been associated with innate protection against malaria infection. However many early studies were inconclusive. We intend to carry out a comprehensive study to investigate the effect of red blood cell differences on the invasion and/or growth of Plasmodium falciparum in vitro using improved techniques. Identification of red cell components involved in interaction with P.falciparum would give a better understanding of host ....Red Cell Polymorphisms and Malaria. Certain red blood cell disorders have been associated with innate protection against malaria infection. However many early studies were inconclusive. We intend to carry out a comprehensive study to investigate the effect of red blood cell differences on the invasion and/or growth of Plasmodium falciparum in vitro using improved techniques. Identification of red cell components involved in interaction with P.falciparum would give a better understanding of host parasite interactions which may in turn suggest novel approaches or pathways to persue. This may eventually lead to the development of novel therapeutics.

Innovative Approaches to Membrane Protein Crystallography & Drug Discovery. Membrane proteins make up around 30% of the predicted products from our human genome, are critical for life, and represent the targets of biological agents like hormones and toxins as well as most drugs. Yet these proteins have persistently defied our best efforts to study them: we know very little about what they do or what they look like. This project is aimed at cracking the problem of membrane proteins, while at the ....Innovative Approaches to Membrane Protein Crystallography & Drug Discovery. Membrane proteins make up around 30% of the predicted products from our human genome, are critical for life, and represent the targets of biological agents like hormones and toxins as well as most drugs. Yet these proteins have persistently defied our best efforts to study them: we know very little about what they do or what they look like. This project is aimed at cracking the problem of membrane proteins, while at the same time developing screening methods that can be used to design drugs against them. The long-term benefits to the community will include fundamental new knowledge and the development of new technologies and pharmaceuticals.Read moreRead less
Monolayer crystallization of membrane proteins. Membrane proteins comprise 25-40% of all proteins and conduct a myriad of finely tuned reactions in every cell. Despite their importance and diversity only ~40 membrane protein structures have been solved, due to the difficulty of producing high quality 2D and 3D crystals. We propose to develop and use the new monolayer crystallization technique, which employs a lipid monolayer as a crystallization template for 2D crystal production.

Despite their importance and diversity only ~40 membrane protein structures have been solved, due to the difficulty of producing high quality 2D and 3D crystals. We propose to develop and use the new monolayer crystallization technique, which employs a lipid monolayer as a crystallization template for 2D crystal production. A number of important membrane proteins are available for these structural studies including ABC transporters, Caveolin-3 and the NS1 protein of Dengue virus, all of which are difficult to crystallize using conventional techniques.Read moreRead less
Disulfide catalysis and protein folding in bacterial virulence. The molecular mechanisms that underpin disulfide bond formation have had a major impact on our understanding of protein folding and function. This project will make a major contribution to fundamental areas of disulfide catalysis pathways in bacterial pathogens and thus help maintain a strong international profile for Australian research in this field. The work will lead to training of research scientists and students in techniques ....Disulfide catalysis and protein folding in bacterial virulence. The molecular mechanisms that underpin disulfide bond formation have had a major impact on our understanding of protein folding and function. This project will make a major contribution to fundamental areas of disulfide catalysis pathways in bacterial pathogens and thus help maintain a strong international profile for Australian research in this field. The work will lead to training of research scientists and students in techniques that include molecular genetics, protein biochemistry and structural biology. Our findings may impact future directions for vaccine research on pathogens that cause life threatening infections in humans and therefore lead to improved health and reduced health care expenditure.Read moreRead less

Summary
Facility for multidimensional fractionation of complex biological mixtures. Acquisition of multidimensional fractionation equipment will allow researchers to separate proteins from complex mixtures, and to compare whole protein profiles of multiple samples. This will permit correlation of specific protein changes associated with infection or disease, a major focus of post-genomic programs of research. The equipment will also provide identification of the key differentiating proteins using mini ....Facility for multidimensional fractionation of complex biological mixtures. Acquisition of multidimensional fractionation equipment will allow researchers to separate proteins from complex mixtures, and to compare whole protein profiles of multiple samples. This will permit correlation of specific protein changes associated with infection or disease, a major focus of post-genomic programs of research. The equipment will also provide identification of the key differentiating proteins using minimal material. Numerous world-class projects and researchers will be able to move more rapidly and reliably from crude cell extracts to identifiable markers, and maintain their competitive positions the recognition of key targets in drug design, disease diagnosis and vaccine development.Read moreRead less

This high throughput monolayer template technology is particularly suited for the structure determination of proteins that are otherwise difficult to crystallize and has clear commercial potential. Membrane protein structures are themselves of value to the biotechnology and pharmaceutical industry for targeted drug design, which could realise benefits in the form of novel medical treatments and reduced side effects. The monolayer template technology will also extend the capabilities of the National Cryo-EM facility, the infrastructure of which, is open for all Australian researchers. Read moreRead less

The world's leading cancer therapeutics have come from the protein phosphorylation field, and glycomics has led to drugs that combat the flu and that stimulate red blood cell production in cancer patients. Thus there is a bright future for discovery of new medicines based on new knowledge in this area. Protein modifications are key to the understanding of disease mechanisms and for searching for new disease markers and new therapeutics. In the hands of local experts the instruments will enable identification of these modifications and provide improved understanding of biology, increase the national competitiveness of Australia's scientists, and provide advanced technology training to the next generation of scientists.Read moreRead less
