Structural elucidation and functional analysis of insulin-like growth factor binding protein-3 domains. Translating information from the human genome project into information about cell function is a major challenge in the post-genome era. The multifunctional insulin-like growth factor binding protein-3 (IGFBP-3), a member of a multigene superfamily, regulates cell growth and function through numerous signalling pathways.

Translating information from the human genome project into information about cell function is a major challenge in the post-genome era. The multifunctional insulin-like growth factor binding protein-3 (IGFBP-3), a member of a multigene superfamily, regulates cell growth and function through numerous signalling pathways. This project will provide structural information about IGFBP-3 as a prototype for the superfamily, and using a combination of methodologies will unravel mechanisms of IGFBP-3 action. The project will advance understanding of IGFBP-3 and superfamily functions, and provide both benefits in international research leadership and economic and health benefits in animal and human growth and metabolism.Read moreRead less
The structure and function of dihydroorotase - an enzyme essential for pyrimidine biosynthesis. Malaria has recently re-emerged as one of the major life threatening diseases worldwide. With increasing travel and climate change, malaria is increasingly endangering Australians at home and abroad. Our work aims to provide the basis for the rational design of a new class of anti-malarial drugs by the systematic and thorough analysis of an essential enzyme in the malarial parasite.
Understanding and changing the mechanism of an enzyme: converting a peptidase to a phosphotriesterase. Enzymes have the ability to catalyse biological reactions rapidly as a consequence of their unique three-dimensional structures. We seek to define the structures of a family of metalloenzymes that are required in most living organisms to activate hormones, degrade unwanted proteins or recycle the protein building blocks for further synthesis. We shall use this information to enhance a second ....Understanding and changing the mechanism of an enzyme: converting a peptidase to a phosphotriesterase. Enzymes have the ability to catalyse biological reactions rapidly as a consequence of their unique three-dimensional structures. We seek to define the structures of a family of metalloenzymes that are required in most living organisms to activate hormones, degrade unwanted proteins or recycle the protein building blocks for further synthesis. We shall use this information to enhance a second function of these enzymes, namely their ability to break down organophosphorus-containing insecticides and nerve agents. Ultimately, the structural information resulting from this project may be used in drug design to regulate blood pressure and in engineering proteins for bioremediation.Read moreRead less

The proposed facility will represent world-leading technology in functional genomics and provide Australian scientists with unique opportunities to identify genes involved in a broad range of biological processes. This will contribute to fundamental knowledge in mammalian biology, and equally importantly, is likely to identify genes involved in important health problems such as cancer, inflammatory disease, brain damage and diabetes. Such genes may in turn constitute targets against which new therapies may be developed. This endeavour will contribute to national research priorities in both the health and scientific/technological development arenas.Read moreRead less

How does clusterin protect cells from stresses? We recently discovered that clusterin: (i) is the only known secreted (ie extracellular) mammalian chaperone and (ii) can protect proteins and cells from stresses.These breakthrough advances provide the first unifying biological function for this protein - in whole organisms, clusterine is likely to protect tissues and organs form biologyical stresses.

We recently discovered that clusterin: (i) is the only known secreted (ie extracellular) mammalian chaperone and (ii) can protect proteins and cells from stresses.These breakthrough advances provide the first unifying biological function for this protein - in whole organisms, clusterine is likely to protect tissues and organs form biologyical stresses. 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
Metalloproteins and metalloenzymes. Most of the chemical reactions and physical movements in living systems are carried out by proteins. The information for producing proteins from amino acids is stored in the genes, but many biological processes depend on additional atoms or molecules ('cofactors') that are added to a protein after it is assembled. For example, more than 30% of all proteins contain metal atoms which are essential for their function. We are studying the structures of such meta ....Metalloproteins and metalloenzymes.

For example, more than 30% of all proteins contain metal atoms which are essential for their function. We are studying the structures of such metalloproteins and metalloenzymes so that we can better understand their activities with long term aims of creating new molecules for biotechnology and/or drugs.Read moreRead less
