Summary
A Cell Sorter Facility for Neuroscience and Related Biotechnology. Neuroscience is entering an era of accelerated discovery in which Queensland neuroscientists can excel if they gain leadership in key technologies. One critical technology is the ability to obtain specific cell populations from various parts of the nervous system in sufficient quantity and purity to enable their accurate examination by gene array, proteomics and physiological techniques. The aim is to establish the world's first ....A Cell Sorter Facility for Neuroscience and Related Biotechnology. Neuroscience is entering an era of accelerated discovery in which Queensland neuroscientists can excel if they gain leadership in key technologies. One critical technology is the ability to obtain specific cell populations from various parts of the nervous system in sufficient quantity and purity to enable their accurate examination by gene array, proteomics and physiological techniques. The aim is to establish the world's first cell-sorting facility dedicated to the production of nerve cells suitable for molecular characterization and screening, providing the basis for identifying key molecules regulating brain function, ageing and repair of great importance to the biotechnology/pharmaceutical industry.Read moreRead less
Signalling cross-talk through Suppressors Of Cytokine Signalling (SOCS) initiates luteolysis in the ovary. Members of the newly discovered SOCS protein family block cytokine signal transduction pathways, including those for prolactin and GH. We have discovered that one of these proteins, SOCS-3, is upregulated in the corpus luteum of the ovary by prostaglandins and propose that induction of prolactin or GH resistance is a hitherto unrecognised and critical step in luteolysis. We have also disco ....Signalling cross-talk through Suppressors Of Cytokine Signalling (SOCS) initiates luteolysis in the ovary. Members of the newly discovered SOCS protein family block cytokine signal transduction pathways, including those for prolactin and GH. We have discovered that one of these proteins, SOCS-3, is upregulated in the corpus luteum of the ovary by prostaglandins and propose that induction of prolactin or GH resistance is a hitherto unrecognised and critical step in luteolysis. We have also discovered that this cross-talk between prostaglandin- and cytokine-receptor signalling pathways occurs in preadipocyte and breast cell lines and propose that this research will serve as a paradigm for understanding how sensitivity to cytokines can be controlled at a molecular level.Read moreRead less
High resolution single particle analysis of biological macromolecules. One of the great challenges of cell biology is to increase the rate of atomic resolution structure determination, particularly of membrane proteins and macromolecular assemblies. The current rate-limiting step is high quality crystal production. Our goal is to prove that protein structures can be determined to atomic resolution by single-particle analysis. 3D structures will be produced by computationally aligning high-resolu ....High resolution single particle analysis of biological macromolecules. One of the great challenges of cell biology is to increase the rate of atomic resolution structure determination, particularly of membrane proteins and macromolecular assemblies. The current rate-limiting step is high quality crystal production. Our goal is to prove that protein structures can be determined to atomic resolution by single-particle analysis. 3D structures will be produced by computationally aligning high-resolution electron microscope images of individual, randomly oriented molecules. The importance of this project is highlighted by the fact over 120,000 protein sequences are already databased, a number set to increase rapidly as new genome sequencing projects are completed.

The molecular basis of macropinocytosis in mammalian cells: the composition of endosome proteins and their function. Individual cells communicate with their immediate environment by the process of macropinocytosis, a process that involves the exchange of materials between the extracellular space and a specialised region of the cell termed endosomes. It is an important process in mammalian cells being essential to the correct functioning of many tissues. This project will advance understanding of ....The molecular basis of macropinocytosis in mammalian cells: the composition of endosome proteins and their function. Individual cells communicate with their immediate environment by the process of macropinocytosis, a process that involves the exchange of materials between the extracellular space and a specialised region of the cell termed endosomes. It is an important process in mammalian cells being essential to the correct functioning of many tissues. This project will advance understanding of macropinocytosis at a molecular level. The project is relevant to understanding the functioning of normal cells and the means by which some pathogens can enter cells and also understanding processes involved in tumour progression and metastasis.Read moreRead less

The aim of this grant is to identify membrane proteins within the mouse genome and annotate their localisation within the cell. Our multi-discipline effort will combine extensive computational prediction strategies with focused cellular biology experimental determination. The underpinning experimental technology, termed reverse transfection arrays, allows for high-throughput assessment of cellular phenotype properties for individual proteins.Read moreRead less

The protein import machinery of peroxisomes. The peroxisome is a subcellular organelle essential for cellular metabolism. Our understanding of the formation, or biogenesis, of the peroxisome has advanced to the stage where many of the proteins involved in this process have been identified. What is less clear is how these proteins interact to form functional macromolecular complexes in the cell. In this project we will use biochemical approaches to isolate protein complexes involved in peroxisome ....The protein import machinery of peroxisomes.
