Understanding the mechanisms that regulate the human signal recognition particle cycle. The precise cellular localisation of proteins is a fundamental process in cell biology required for survival. The aim of this project is to understand the mechanisms by which the human signal recognition particle delivers newly translated proteins to their cognate cellular location.
Explaining the differences in affinity and of carbohydrate binding of the glycogen-sensing enzyme, AMP-protein activated kinase (AMPK). This project will provide fundamental molecular knowledge of how a complex enzyme, AMPK is controlled by the major sugar molecule, glycogen. Our research will increase our understanding of its role in metabolic diseases such as Type 2 diabetes and obesity.
Understanding the role of methionine oxidation in amyloid formation. Amyloid deposition is associated with many debilitating systemic and neurological diseases, including Alzheimer's disease. This project aims to understand the effect of protein oxidation on the process of amyloid fibril formation. This knowledge will assist in the discovery of the triggers of these disorders and may identify methods of combating them.
Improved patient care and image resolution in magnetic resonance imaging. A better understanding of the vibration within MRIs would result in techniques to both improve the image resolution and lower the noise emissions. Direct improvement of health care for Australians will result. Both the patient and the working environment around these scanners will improve as well as image resolution. Presently imaging is possible at the cellular scale, but only through improved MRI stability will imaging r ....Improved patient care and image resolution in magnetic resonance imaging. A better understanding of the vibration within MRIs would result in techniques to both improve the image resolution and lower the noise emissions. Direct improvement of health care for Australians will result. Both the patient and the working environment around these scanners will improve as well as image resolution. Presently imaging is possible at the cellular scale, but only through improved MRI stability will imaging reach the molecular level. Medical research that is linked to MRI imaging can be expected to advance in step with improved image resolution. The resulting knowledge could also be used in other research and industrial areas, including micro- and nano-scale devices, where vibration is a critical performance limiting factor.Read moreRead less
Structural analysis of a novel plasma membrane coat complex. The plasma membrane of mammalian cells forms a crucial barrier between the cell and the outside world. This project investigates how a newly-discovered family of proteins work together to generate specialised regions of the plasma membrane called caveolae.
Structural basis for the assembly of caveolae. Caveolae are small invaginations of the plasma membrane and are a characteristic feature of eukaryotic cells. Described morphologically in the early 1950s their many important functions are only just beginning to be revealed. Caveolae are multifunctional organelles that play a vital role in normal cellular processes such as signalling and membrane homeostasis, and are perturbed in cancer, lipid storage and muscle diseases. A new family of coat prote ....Structural basis for the assembly of caveolae. Caveolae are small invaginations of the plasma membrane and are a characteristic feature of eukaryotic cells. Described morphologically in the early 1950s their many important functions are only just beginning to be revealed. Caveolae are multifunctional organelles that play a vital role in normal cellular processes such as signalling and membrane homeostasis, and are perturbed in cancer, lipid storage and muscle diseases. A new family of coat proteins called cavins have recently been discovered. Cavins are essential for the formation of caveolae, and this project seeks to understand how these multiprotein complexes are assembled at the membrane interface and control caveola function at the molecular level.Read moreRead less
Neuroimage as biomechanical model: new real-time computational biomechanics of the brain. This project is to extend to medicine the success computational mechanics has enjoyed in traditional engineering. The project will create enabling modelling and computing technologies for Computer-Integrated Surgery Systems that could help to improve clinical outcomes and the efficiency of health care delivery.
Determination of lung morphology from X-ray phase contrast radiographs. Current methods of imaging the lung rely heavily on low contrast images obtained with chest radiography or computed tomography. This research will develop new X-ray phase contrast imaging techniques capable of providing a tenfold contrast increase over conventional chest radiography at a fraction of the X-ray dose of computed tomography. Methods of extracting quantitative information on lung morphology and pathology from pha ....Determination of lung morphology from X-ray phase contrast radiographs.

This research will develop new X-ray phase contrast imaging techniques capable of providing a tenfold contrast increase over conventional chest radiography at a fraction of the X-ray dose of computed tomography. Methods of extracting quantitative information on lung morphology and pathology from phase contrast chest radiographs will be developed during this research. Eventual outcomes are likely to lead to improved methods of detecting lung disease and injury for both biomedical and clinical studies.Read moreRead less
"Painting" the 3D proteome: folding, conformation and interactions. The project aims to develop a "residue painting approach", employing novel chemical biology reagents and advanced quantitative proteomics, to monitor changes in protein folding, conformations and interactions in cells, in response to stimuli. Proteins direct almost all functions required to sustain life. The project expects to map the dynamic 3D-structures of thousands of proteins that inform the networks they are in, and of the ...."Painting" the 3D proteome: folding, conformation and interactions.

Proteins direct almost all functions required to sustain life. The project expects to map the dynamic 3D-structures of thousands of proteins that inform the networks they are in, and of the conformations they adopt. Expected outcomes include the development of novel biotechnology tools for protein structure and function analysis, the illumination of important cell biology pathways underpinning molecular responses to stimuli and stress, and the training of our next generation of scientists.Read moreRead less
