Summary
Primary open angle glaucoma is the most common form of glaucoma. In this project we will focus on the identification of functional genetic variants influencing development of this disorder, using a powerful whole exome sequencing approach in a large multigenerational pedigree from the Norfolk Island population isolate. The identification of genes influencing glaucoma development would provide invaluable clues to aid in defining the pathophysiology of this common disease.
Identifying Key Players In The Spread Of Antimicrobial Resistance

Summary
Antibiotic drugs are essential to treat bacterial infections. However some bacteria have genes that allow them to resist certain drugs, which can be transferred among bacteria to create 'superbugs' that can resist nearly all the drugs we have. This project investigates the transfer of drug resistance genes between Gram negative bacteria (common agents of food poisoning, hospital infection, UTI, etc) and aims to identify the bacteria and genes most important in the spread of superbugs in Australi ....Antibiotic drugs are essential to treat bacterial infections.

Assembly And Function Of Two Interacting Oncogenic Scaffolds

$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

National Health and Medical Research Council
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.
Spatial And Temporal Dimensions Of Mu-opioid Receptor Signalling: Implications For The Development Of Tolerance
Funder
National Health and Medical Research Council
Funding Amount
$799,316.00
Summary
The use of morphine as an analgesic is still limited by undesirable side effects such as tolerance. Despite decades of research, the mechanisms behind the development of tolerance are poorly understood. The ? opioid receptor is a protein expressed at the surface of the cells that is the target of morphine. This project will investigate the signalling events triggered by opioids with unprecedented resolution and will aim to elucidate why morphine elicits more tolerance than other opioid drugs.
Understanding The Function And Regulation Of G Protein-coupled Receptor Signalosomes And Their Role As High Resolution Signalling Platforms

Funding Amount
$566,588.00
Summary
G protein-coupled receptors are specialised proteins located on the surface of cells. They are the targets of 50% of currently available pharmaceuticals, but these drugs are derived from limited knowledge of only a fraction of proteins. This proposal will examine exciting and novel properties of receptors that only occur following the assembly of the proteins into specialised networks within cells. The new information will expand our current knowledge, and facilitate future targeted drug design.
STABILISING G PROTEIN-COUPLED RECEPTORS FOR DRUG DISCOVERY

Funding Amount
$628,140.00
Summary
Prescription drugs targeting human proteins called GPCRs are sold as effective treatments for many diseases. However, there are over 800 different types of GPCRs in the human body and only a small fraction is targeted by drugs, mainly because GPCRs are unstable and thus difficult to work with in the laboratory. We are applying newly developed technologies to engineer stabilised ?1-adrenoceptors, a class of GPCRs, for drug discovery against cardiovascular diseases, epilepsy and neurodegeneration
Exploring Scanning Ultrasound (SUS), A Novel Method To Treat And Prevent Neurodegenerative Disease
Funder
National Health and Medical Research Council
Funding Amount
$765,708.00
Summary
We developed a novel scanning ultrasound (SUS) protocol that clears toxic protein aggregates and restores memory function in mouse models of Alzheimer's disease (AD), without the need for therapeutic agents. Here we aim to determine whether SUS has preventative potential, whether there are synergistic effects, and whether a therapeutic antibody combined with SUS leads to an enhanced therapeutic outcome. Together this will guide the development of an ultrasound therapy in AD patients.
Function And Inhibition Of Plasmepsin V In Targeting Malaria Virulence Proteins Into Human Erythrocytes

Summary
Malaria parasites dramatically renovate infected erythrocytes to survive and evade the host immune system by delivering hundreds of exported parasite proteins into the cell. The parasite protease Plasmepsin V is essential for protein export. We aim to develop potent inhibitors of this protease in the hope of blocking its function and killing the parasite. We also aim to discover the components of the trafficking pathway after cleavage by Plasmepsin V that sorts virulence proteins to the host cel ....Malaria parasites dramatically renovate infected erythrocytes to survive and evade the host immune system by delivering hundreds of exported parasite proteins into the cell.

Many of the most serious diseases of Western societies including obesity, Type 2 diabetes, cancer growth and metastasis and cardiovascular disease have metabolic dimensions. The enzyme AMPK regulates cellular and whole body energy homeostasis by coordinating metabolic pathways to balance energy demand with nutrient supply. We are studying the structure and function of AMPK with the aim of better treating metabolic diseases.
