Plasmonic nanoparticles for probing and perturbing the spatial organisation of membrane proteins. Receptors on the surface of cells provide vital functions and represent a large fraction of drug targets. It is believed that the spatial organisation of receptors can effect their function. This project will test this hypothesis by combining nanotechnology with biophysics to watch and manipulate the spatial organisation of receptors.
Elucidating the determinants of cation import across the kingdoms of life. The metal ion manganese is essential to all forms of life. This project aims to investigate how this poorly abundant cation is selectively acquired from the chemical complexity of the environment for import into cells by using state-of-the-art biochemical and microbiological techniques. This project expects to define the fundamental basis for how bacterial, archaeal and eukaryotic plastid cation-selective importers can di ....Elucidating the determinants of cation import across the kingdoms of life. The metal ion manganese is essential to all forms of life. This project aims to investigate how this poorly abundant cation is selectively acquired from the chemical complexity of the environment for import into cells by using state-of-the-art biochemical and microbiological techniques. This project expects to define the fundamental basis for how bacterial, archaeal and eukaryotic plastid cation-selective importers can discriminate manganese from chemical similar cations to achieve selective uptake. The expected outcomes of this work will be an understanding of the fundamental basis for selective metal import in biological systems. This should provide benefits for industry through synthetic biological applications of this knowledge. Read moreRead less
Nicotinic receptor structure and function probed with conotoxins. Nicotinic receptors are intrinsic membrane proteins that play a role in communication in excitable cells, particularly in the nervous system. The primary goals of this project are to define the structural and functional determinants of nicotinic-conotoxin interactions at a molecular level, and develop new selective probes that advance neurophysiological research.

The biogenesis of bacterial outer membranes; how bacteria build their surface membranes. The outer membrane protects probiotic bacteria in the human intestine and enables pathogenic bacteria to cause infectious diseases. We will determine bacteria build their outer membranes - outstanding training opportunities come through cutting edge technology and the development of skills not common in Australia.

Nanoscale characterisation of the dynamics of artificial lipid membranes - model systems for drug binding studies. This project will see the development of artificial membranes replicating the physiological behaviour of cell membranes providing a novel platform for in vitro drug evaluation clearing the way for the development of effective new therapies with fewer side effects.
Resolving the Structures of Human Muscarinic M1 and M4 Receptors. Muscarinic receptors are vital for most basic human brain functions. These receptors are changed in schizophrenia and Alzheimer's disease. This project will determine the structure and localisation of two of these receptors in order to i) understand their roles in brain disorders and ii) develop drugs to treat disorders involving them.
Molecular mechanisms for copper trafficking across membranes. Copper is a trace metal that is essential for all forms of life, however it is toxic in excess. Tightly controlled protein-based metalloregulatory systems are responsible for copper uptake and homeostasis in all cells. Components of these systems are integral membrane transport proteins, which include the Ctr proteins that are solely responsible for copper uptake into eukaryotic cells. This project aims to define the molecular mechani ....Molecular mechanisms for copper trafficking across membranes.

Components of these systems are integral membrane transport proteins, which include the Ctr proteins that are solely responsible for copper uptake into eukaryotic cells. This project aims to define the molecular mechanisms by which the Ctr proteins transport copper across eukaryotic cell membranes, by solving their three-dimensional structures by X-ray crystallography.Read moreRead less
