The aim of this project is to determine the mechanisms of protein-mediated potassium ion transport across cell membranes. It will combine advanced simulations, structural biology and electrophysiology to describe the detailed molecular processes underscoring calcium-activated potassium channel conduction, gating and inactivation. The expected outcome is an improved description of how ion channels recognise and respond to physiological stimuli to control electrical signalling the body. Our results will provide benefits in the form of basic understanding relevant to ion transport phenomena in biological systems, and atomic-level views of nervous system function to guide future directions in pharmacology.Read moreRead less

Summary
Innovative chemical tools for the isolation, biochemical and structural analysis of biological macromolecular assemblies. This project will develop a new approach for determining the three dimensional structures of protein complexes. This project will demonstrate this approach by determining the structure of a protein complex involved in gene regulation and disease.
High-throughput microfluidic approach to mapping hierarchies of interactions in the gene regulation machinery. The exploration of protein-protein interactions networks is becoming an extremely active area of research in life sciences. The current project will develop new approaches to accelerate the discovery of novel interacting proteins participating in gene regulation, in order to understand how cells differentiate into different tissues and organs.
Coproantigen detection tests for diagnosis of intestinal parasitic nematode infection. The aim of this project is to develop new tests for detection of hookworm and Strongyloides, two common intestinal worm infections of humans. These tests offer the potential to replace current tests, namely stool microscopy and serodiagnosis, both of whose performance is unsatisfactory due to deficiencies in sensitivity, specificity and operator convenience. The tests will rely on monoclonal antibodies to dete ....Coproantigen detection tests for diagnosis of intestinal parasitic nematode infection. The aim of this project is to develop new tests for detection of hookworm and Strongyloides, two common intestinal worm infections of humans. These tests offer the potential to replace current tests, namely stool microscopy and serodiagnosis, both of whose performance is unsatisfactory due to deficiencies in sensitivity, specificity and operator convenience. The tests will rely on monoclonal antibodies to detect parasite products in stool. Such testing technology is amenable to configuration in a robust format, suitable for large-scale manufacture. Given the worldwide prevalence of these parasites, the tests will have a market potential of international significance.Read moreRead less

Single molecule imaging laboratory: The goal of the project is to establish a single molecule imaging laboratory to close the gap between structural imaging and cellular imaging. Utilising the expertise of the ARC Centre of Excellence in Advanced Molecular Imaging, the aim of the project is to design, build and apply three microscopes that go beyond the current commercial solutions for single molecule localisation microscopy such as Photo-Activation Localisation Microscopy (PALM) and Stochastic Optical Reconstruction Microscopy (STORM) and perform single molecule imaging: deep inside cells and tissue.The facility will have a fast acquisition rate to monitor highly dynamic molecular events, and improved precision to image molecules and complexes in intact cells with less than or equal to one nanometre resolution. There is currently no comparable imaging facility in the world.Read moreRead less

This project aims at expanding the pool of drug targets, by extending drug screening to protein-protein interaction networks. This project aims to assemble a novel technical platform to detect binding between proteins, using a combination of cell-free protein expression, AlphaScreen and single-molecule fluorescence. This pipeline has great potential to accelerate the exploration of protein networks, and provides also a generic platform for drug screening on difficult targets. The project intends to screen Phylogica's libraries of peptides called Phylomers to discover tight binders to a Transcription Factor, Sox18. The objective of this project is to determine which Phylomers can disrupt specific interactions between Sox18 and its binding partners involved in lymphangiogenesis.Read moreRead less
A microfluidic array of phylomers for rapid discovery of peptide probes and biomarkers. This project, through an alliance with Phylogica, aims at exploiting a unique source of structural diversity for drug discovery, harvesting the creativity of nature in its most exotic places. The project will develop a novel approach to validate design and validate drug candidates, by gathering them on a single screening chip for a powerful discovery platform.

Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyamines, as we have discovered that polyamines are regulated by iron at 2-major levels, involving >10-key polyamine pathway proteins. This proposal represents first-in-field studies specifically designed to dissect mechanisms involved in this relationship. Our Central Hypothesis is that iron regulates polyamine metabolism.Read moreRead less

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less
