The University of Sydney will own any intellectual property arising from this work and will benefit from the commercialisation of hydrophobin-based products.Read moreRead less
Allosteric regulation, molecular structure and function of transglutaminase 2. With Australia's ageing population, we can expect to see increasing prevalence of pathologies such as cancer, Alzheimer's disease, and cataracts. The ubiquitous enzyme transglutaminase 2 (TG2) has been implicated in all of these age-related diseases, as well as in chronic disorders such as coeliac disease and diabetes, and may contribute in a positive way to wound healing. Understanding how TG2 is activated and inac ....Allosteric regulation, molecular structure and function of transglutaminase 2. With Australia's ageing population, we can expect to see increasing prevalence of pathologies such as cancer, Alzheimer's disease, and cataracts. The ubiquitous enzyme transglutaminase 2 (TG2) has been implicated in all of these age-related diseases, as well as in chronic disorders such as coeliac disease and diabetes, and may contribute in a positive way to wound healing. Understanding how TG2 is activated and inactivated, and how it selects its targets, will be a critical addition to current knowledge of this enzyme, and will be an essential prerequisite for the development of TG2-targetted drugs and other TG2-related therapies.Read moreRead less
Guarding and evolving the genome: interactions between DNA-repair enzymes and damaged DNA. The application of structural biology techniques to the area of DNA repair allows us to understand the full implications linking genes and proteins to the molecular mechanisms of diseases such as cancer and hereditory conditions. Studies in this highly internationally competitive area are already established in the Bond laboratory, which has recently relocated to Australia. The use of forward-thinking stru ....Guarding and evolving the genome: interactions between DNA-repair enzymes and damaged DNA. The application of structural biology techniques to the area of DNA repair allows us to understand the full implications linking genes and proteins to the molecular mechanisms of diseases such as cancer and hereditory conditions. Studies in this highly internationally competitive area are already established in the Bond laboratory, which has recently relocated to Australia. The use of forward-thinking structural biology approaches to solve difficult technical problems will foster collaborations within Australia and with leading laboratories abroad, providing excellent up-to-date research training for students and postdoctoral researchers.

Linkage Infrastructure, Equipment And Facilities - Grant ID: LE100100236
Funder
Australian Research Council
Funding Amount
$180,000.00
Summary
Facilities for spectroscopy and diffraction at high pressures. The provision of infrastructure for the study of novel materials under high pressures will enhance Australia's capability in creating new materials and in creating new devices that meet needs in communication, environment and medicine applications. The new facility will enable researchers to understand the response of structures to extreme pressures and will exploit the unique capabilities of the synchrotron light.
Characterisation of two-pore domain potassium channels: structure-function studies of the M1-P1 loops of TASK channels. TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers. The in depth structural and functional character ....Characterisation of two-pore domain potassium channels: structure-function studies of the M1-P1 loops of TASK channels. TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers. The in depth structural and functional characterisation of this class of potassium channels is of great importance as they are interesting targets for new therapeutic developments. Advancement of knowledge in the structure and function of these channels will underpin drug targeting that will aid preventative healthcare, allowing Australians to age well and age productively.Read moreRead less
Investigating the mechanisms of flavonoid actions on glycine receptors. The research to be conducted in this project will use state-of-the-art electrophysiological and molecular biological approaches to carefully characterise the actions of certain flavonoid compounds on the glycine-receptor channel. These compounds have recently been reported to act as modulators of ligand-gated ion channels, proteins integral to brain function and disease. However, no-one has studied in any detail the mechan ....Investigating the mechanisms of flavonoid actions on glycine receptors. The research to be conducted in this project will use state-of-the-art electrophysiological and molecular biological approaches to carefully characterise the actions of certain flavonoid compounds on the glycine-receptor channel. These compounds have recently been reported to act as modulators of ligand-gated ion channels, proteins integral to brain function and disease. However, no-one has studied in any detail the mechanisms by which these compounds act. By discovering their site and mechanisms of action we will further our understanding of these important proteins and their modulation, maintain Australia's significant expertise in this field and provide leads for future development of drugs with potential therapeutic value.Read moreRead less
Postgenomic perspectives on human nature. The rapid growth of biological knowledge and the need for societal reflection on this knowledge and its applications in Australia and overseas make it increasingly urgent that the humanities and social sciences draw on a biologically credible vision of human nature. We will study how non-scientists understand human nature and compare their ideas to those of scientists from a range of different disciplines. We will examine what current biology reveals abo ....Postgenomic perspectives on human nature. The rapid growth of biological knowledge and the need for societal reflection on this knowledge and its applications in Australia and overseas make it increasingly urgent that the humanities and social sciences draw on a biologically credible vision of human nature. We will study how non-scientists understand human nature and compare their ideas to those of scientists from a range of different disciplines. We will examine what current biology reveals about the biological basis of human characteristics and develop an account of human nature that is defensible in the light of that knowledge.Read moreRead less
Defining mechanisms of action of novel alpha-conotoxins at nicotinic receptor-channels. Marine snails from the waters off the Australian coast produce an amazing variety of mini-proteins in their venoms called conotoxins that they use to capture prey. These conotoxins bind very specifically to receptors in our body associated with the transmission of nerve signals. We will use natural and synthetically modified conotoxins to selectively block particular types of neuronal 'receptors' to gain a gr ....Defining mechanisms of action of novel alpha-conotoxins at nicotinic receptor-channels. Marine snails from the waters off the Australian coast produce an amazing variety of mini-proteins in their venoms called conotoxins that they use to capture prey. These conotoxins bind very specifically to receptors in our body associated with the transmission of nerve signals. We will use natural and synthetically modified conotoxins to selectively block particular types of neuronal 'receptors' to gain a greater understanding of how the nervous system functions. This knowledge will help in the design of new drugs to treat a variety of diseases and disorders. Essentially we will use a chemical armoury developed by the cone snail to design state-of-the-art mini-protein drugs.Read moreRead less
