Funding Amount
$316,449.00
Summary
This project aims to understand how certain animal toxins that cause analgesic and pesticidal effects in model animals interact with biological ion channels in atomistic detail using computational techniques. By understanding the detailed molecular interactions involved in the binding of the toxins to channels, toxin variants with improved potency and specificity may be designed as promising templates for novel analgesics and pesticides.
Mechanisms Of Gene Regulation - Structure, Function And Design

Funding Amount
$697,209.00
Summary
The human genome contains at least 20000 genes. The activity of these genes must be tightly controlled throughout an individual’s life and problems with the regulation of genes lie at the heart of many common and serious diseases, including most forms of cancer. My program of research is focused on understanding the mechanisms underlying gene regulation and on the design of new reagents that could be used to manipulate the activity of genes that behave aberrantly in disease states.
Structure And Function Of A Cancer-linked Co-regulator Complex
Funder
National Health and Medical Research Council
Funding Amount
$1,282,475.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
Oligomers Of The Alzheimer's Amyloid-? Peptide: Structure, Mechanism Of Toxicity And Small Molecule Interactions

Funding Amount
$356,324.00
Summary
Alzheimer’s disease is a devastating neurodegenerative disease that currently affects 240 000 Australians. The protein called amyloid-? is found in deposits in the brains of Alzheimer’s patients. The toxic form of this protein is thought to be small aggregated particles called ‘oligomers’. This work aims to investigate the structure of these particles, the reason why they are toxic, as well as their interaction with the neuroprotective compound EGCG, which is found in green tea.

Assembly And Function Of Two Interacting Oncogenic Scaffolds

Funding Amount
$705,585.00
Summary
Aberrant signaling by the protein kinase superfamily is a known driving force for many cancers and inflammatory diseases. Recently, a subset of kinase-like proteins, termed pseudokinases, have emerged as crucial regulators of kinase signalling pathways. This proposal focuses on elucidating the scaffolding function and assembly of two pseudokinases, termed SgK223 and SgK269, which display oncogenic properties and aims to understand how their signalling abilities are subverted in a disease state.
Design And Engineering Of Adnectins For Diagnosis And Therapy

Funding Amount
$803,152.00
Summary
This project aims to engineer a naturally-occurring human protein, called an adnectin, to produce molecules that are able to bind specific targets in the human body, and as such may be used in the diagnosis and therapy of a range of diseases.
Endosomal Protein Trafficking Complexes - Therapeutic Targets For Novel Antivirals
Funder
National Health and Medical Research Council
Funding Amount
$543,727.00
Summary
The enzyme Vps4 is a key target for the development of new antiviral drugs targeting a family of enveloped viruses that includes HIV (17,000 cases), Hepatitis B and C (420,000 cases) and Herpes Simplex (type I, II - 1.3 million cases). This project will use high resolution microscopy to investigate the molecular structures that enable infection by these and other Vps4-dependent enveloped viruses.
I am a biochemist focussed on understanding how the structures of proteins determine their functions. I intend to apply this understanding to medically relevant questions by working collaboratively and using a range of complementary structural, computational and cell biology techniques. In particular, I will focus on proteins involved in infection and immunity, to understand how they work, and contribute to the development of drugs and vaccines.
LMO2-containing Complexes In Leukemia And Blood Cell Development

Funding Amount

Summary
Childhood T-cell leukemias have a poor prognosis for recovery. We are determining, with atomic level precision, how the proteins Lmo2 (also linked to prostate and other cancers) and Tal1, and their binding partners contribute to both normal blood cell development and T-cell leukemia. With this information we are developing reagents that can be used to disrupt disease-causing complexes, and which will lead towards the development of new, specific, therapeutics for leukemias and other cancers.
