Summary
Rett syndrome (RTT) is the second most common cause of severe mental retardation in girls and women. Although two genes (MECP2 and CDKL5) responsible for RTT have been identified, we still do not understand how these genes affect brain function. The focus of this research project is to identify which proteins are controlled by CDKL5, with the express hope that a better understanding of these processes will allow us to design specfic therapies for this untreatable devasting disorder.
The Structural Basis Of Ligand-Induced Activation Of The Insulin Receptor

Summary
We aim to understand how insulin binds to and activates its cell-surface receptor. This information has implications for the design of anti-diabetic agents targetted directly to the insulin receptor. Diabetes is a global health problem and is classified by the World Health Organization as an epidemic. The results also have implications for the insulin-like growth factor receptor system and the design of anti-cancer therapeutics directed towards it .
Structural Basis Of Ligand Binding To Type 1 Insulin-like Growth Factor Receptor (IGF-1R)

Summary
Insulin-like growth factors are involved in normal growth and development. However, they are also implicated in cancer development and progression. We are seeking to understand the way in which these growth factors bind to their receptor on the surface of the cell and stimulate the cell to survive, proliferate and migrate to new tumour sites. Such knowledge will be useful in the design of molecules that could potentially intervere with this process and thus be used as anti-cancer therapeutics.

Summary
Cells require numerous signalling pathways to keep various cellular processes coordinated and under control. One of the most important aspects of signalling is formation of complexes involving two or more different proteins. One of the recently identified players in the formation of these signalling complexes is the so-called forkhead-associated (FHA) module, FHA modules are protein sequences of ~130 amino acids that appear as a part of signalling proteins and bind to specific sequences on signa ....Cells require numerous signalling pathways to keep various cellular processes coordinated and under control. One of the most important aspects of signalling is formation of complexes involving two or more different proteins. One of the recently identified players in the formation of these signalling complexes is the so-called forkhead-associated (FHA) module, FHA modules are protein sequences of ~130 amino acids that appear as a part of signalling proteins and bind to specific sequences on signalling protein partners. Many proteins containing FHA modules are important for the repair of damaged DNA and the stability of chromosomes. The aim of our studies is to understand the molecular and atomic details of how FHA modules bind their partners. This is the first step towards designing therapeutic agents against various forms of cancer where DNA is damaged.Read moreRead less
A hierarchical quantum mechanical and classical simulation of biological ion channels. I aim to develop a methodology incorporating molecular quantum
mechanics and classical Brownian mechanics in a way that can be
applied practically to large macromolecular systems, thus relating
fine structural details to experimentally measurable
properties. Specifically, I will apply this methodology to study ion

applied practically to large macromolecular systems, thus relating

properties. Specifically, I will apply this methodology to study ion
channels in which the challenge is to relate electronic and atomic
structure to the conductance properties of the channel. Accurately
determining these relationships provides a pathway to developing cures
for many neurological, cardiac, and muscular diseases.

A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how the ....A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how these cell signaling proteins are organized into pathways and how this microorganism controls its complex growth and developmental cycle, we will be able to develop novel methods of control. We are at the fore front of international research and therefore uniquely placed to conduct this project.Read moreRead less
Targeting genes elevated in the athlete's heart to improve function of the failing heart. Cardiovascular disease affects about 3.7 million Australians and heart failure ranks as one of the major killers, representing a huge burden on our health care system and economy. This situation is likely to get worse with an increasing ageing population. Current therapeutics for heart failure patients largely delay disease progression but generally fail in significantly improving heart function and quality ....Targeting genes elevated in the athlete's heart to improve function of the failing heart. Cardiovascular disease affects about 3.7 million Australians and heart failure ranks as one of the major killers, representing a huge burden on our health care system and economy. This situation is likely to get worse with an increasing ageing population. Current therapeutics for heart failure patients largely delay disease progression but generally fail in significantly improving heart function and quality of life. The proposal has focused on targeting the protective effects of 'good' heart growth by identifying genes elevated in the heart in response to exercise. Targeting genes elevated in the athlete's heart to improve function of the failing heart represents a new strategy for the treatment of heart failure.Read moreRead less
