The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Structural analysis of membrane proteins using template-mediated crystallization. A new frontier technology will be developed in the form of a systematic crystallization pipeline for membrane proteins. This high throughput monolayer template technology is particularly suited for the structure determination of proteins that are otherwise difficult to crystallize and has clear commercial potential. Membrane protein structures are themselves of value to the biotechnology and pharmaceutical industry ....Structural analysis of membrane proteins using template-mediated crystallization. A new frontier technology will be developed in the form of a systematic crystallization pipeline for membrane proteins. This high throughput monolayer template technology is particularly suited for the structure determination of proteins that are otherwise difficult to crystallize and has clear commercial potential. Membrane protein structures are themselves of value to the biotechnology and pharmaceutical industry for targeted drug design, which could realise benefits in the form of novel medical treatments and reduced side effects. The monolayer template technology will also extend the capabilities of the National Cryo-EM facility, the infrastructure of which, is open for all Australian researchers. Read moreRead less
Protein degradation in mammals. One mechanism by which the regulation of protein turnover occurs is the balance between the activity of enzymes responsible for the ubiquitination and deubiquitination of target proteins. The majority of targets of this second family of enzymes are unknown. This project proposes a method for the identification of the targets of two specific mammalian deubiquitinating enzymes in order to understand their function and to begin to explore this new research field. ....Protein degradation in mammals. One mechanism by which the regulation of protein turnover occurs is the balance between the activity of enzymes responsible for the ubiquitination and deubiquitination of target proteins. The majority of targets of this second family of enzymes are unknown. This project proposes a method for the identification of the targets of two specific mammalian deubiquitinating enzymes in order to understand their function and to begin to explore this new research field. Knowledge about this new aspect of protein degradation could provide a powerful tool to test the effect of the stabilisation or removal of specific proteins in the cell and also to develop new technologies in protein production.Read moreRead less
New Antioxidants Impacting on ROS and Free Radical Mediated Cellular Damage and Disease. Oxidative stress describes the condition where free radicals damage cells and biological systems and this stress underlies many diseases including neurological conditions and aging disorders such as Alzheimer's Disease. This project sets out to create new forms of powerful antioxidant drugs able to probe the mechanisms of such diseases with the view to developing new treatments and therapies.
Interactions of Insulin-like Growth Factors and their Binding Proteins with Vitronectin: a structural basis for antagonist design and development. Tissue Therapies Ltd has shown that a patented combination of three biosynthetic molecules, VitroGroR, can promote tissue repair effectively. This project will use biophysical and biochemical techniques to investigate precisely how these molecules interact, and hence provide a rational basis for future developments and improvements of this exciting n ....Interactions of Insulin-like Growth Factors and their Binding Proteins with Vitronectin: a structural basis for antagonist design and development. Tissue Therapies Ltd has shown that a patented combination of three biosynthetic molecules, VitroGroR, can promote tissue repair effectively. This project will use biophysical and biochemical techniques to investigate precisely how these molecules interact, and hence provide a rational basis for future developments and improvements of this exciting new therapeutic strategy.
Conversely, this information would also facilitate the development of antagonists to VitroGroR complexes would provide novel opportunities to treat diseases such as cancer and atherosclerosis that involve excessive production of its component molecules.Read moreRead less
Regulation and function of a novel protein tyrosine phosphatase. A cell's ability to respond to its extracellular environment involves a complex and highly organised series of events referred to as cellular signalling. These signalling processes regulate fundamental cellular processes that underlie the growth and development of all living organisms. This proposal focuses on a group of enzymes known as the protein tyrosine phosphatases and their ability to regulate tyrosine phosphorylation-depe ....Regulation and function of a novel protein tyrosine phosphatase. A cell's ability to respond to its extracellular environment involves a complex and highly organised series of events referred to as cellular signalling. These signalling processes regulate fundamental cellular processes that underlie the growth and development of all living organisms. This proposal focuses on a group of enzymes known as the protein tyrosine phosphatases and their ability to regulate tyrosine phosphorylation-dependent signalling. We have identified a novel human protein tyrosine phosphatase and we aim to characterise its regulation and biological function.Read moreRead less
Structural studies of the interactions of actinin-4 and intracellular signalling proteins. The intracellular signalling cascade plays important roles in cellular processes such as growth and differentiation by exerting changes in gene expression or remodelling of the intracellular protein framework. The actin-based cytoskeleton is one such network of proteins responsible for a number of processes including cell division, migration and adhesion to other cells and tissues. This proposal aims to un ....Structural studies of the interactions of actinin-4 and intracellular signalling proteins. The intracellular signalling cascade plays important roles in cellular processes such as growth and differentiation by exerting changes in gene expression or remodelling of the intracellular protein framework. The actin-based cytoskeleton is one such network of proteins responsible for a number of processes including cell division, migration and adhesion to other cells and tissues. This proposal aims to understand how actinin-4, a component of the actin cytoskeleton in non-muscle tissues, interacts with and is stimulated by proteins of the intracellular signalling cascade.Read moreRead less
