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.

Summary
800 MHz NMR spectrometer for biomolecular structure-function analysis. An understanding of how organisms function at the molecular level is central to developing the ability to fight many diseases in a rational way. This equipment will provide the capability for many different laboratories around NSW and the ACT to advance our knowledge at this fundamental level, primarily by examining the structures and functions of biomolecules such as proteins.
Understanding mechanistic and systemic regulation of protein prenyltransferases. The proposed research will expand our understanding of lipid-conjugating enzymes that are critical for a multitude of normal cellular functions. We seek to reveal the basic workings of cells and help to explain the development and complexity of signalling networks in eukaryotic evolution. The findings will enable us to explore and exploit the catalytic properties of these lipid-related enzymes for applications in bi ....Understanding mechanistic and systemic regulation of protein prenyltransferases.

We seek to reveal the basic workings of cells and help to explain the development and complexity of signalling networks in eukaryotic evolution. The findings will enable us to explore and exploit the catalytic properties of these lipid-related enzymes for applications in biotechnology. The ultimate aim is to create novel technologies for protein production, modification and analysis that will accelerate the pace of discovery in protein research, basic cell and organism biology, diagnostics, biotechnology and drug discovery.

Proteomic analysis of subcellular changes during apoptosis. This project aims to use a novel proteomic approach to examine mechanisms of apoptosis at the level of the plasma membrane, mitochondrion, nucleus and cytosol, screening protein extracts of cell organelles by the new technique of SELDI-TOF mass spectrometry in which proteins are adsorbed onto activated chips. This will provide protein mass profiles characteristic of various stages of apoptosis, and will allow identification of proteins ....Proteomic analysis of subcellular changes during apoptosis. This project aims to use a novel proteomic approach to examine mechanisms of apoptosis at the level of the plasma membrane, mitochondrion, nucleus and cytosol, screening protein extracts of cell organelles by the new technique of SELDI-TOF mass spectrometry in which proteins are adsorbed onto activated chips. This will provide protein mass profiles characteristic of various stages of apoptosis, and will allow identification of proteins of interest by conventional proteomic methods. The establishment of SELDI-MS as a viable tool for cell proteomics would open new opportunities to understand a broad range of cellular functions at the level of protein expression.Read moreRead less

The facility will allow new approaches to identifying novel natural products and understanding cell signalling pathways. Knowledge of these pathways and the identification of molecules that can affect them are keys to understanding normal cellular physiology and identifying drug-like molecules able to inhibit malfunctioning pathways found in different disease such as cancer. The facility will accellerate drug discovery and basic research in cell biology and underpin National Research Priorities.Read moreRead less
Evolution of a protein fold from toxin to physiological regulator: an endogenous potassium channel blocker in humans. A potassium channel blocking peptide employed by sea anemones as a toxic component of their venom is also found in proteins from a number of higher organisms, including man. In most of these proteins the function of this toxin domain is unknown. This project aims to define the structure and function of this domain in a human protein, matrix metalloprotease 23, which has possible ....Evolution of a protein fold from toxin to physiological regulator: an endogenous potassium channel blocker in humans. A potassium channel blocking peptide employed by sea anemones as a toxic component of their venom is also found in proteins from a number of higher organisms, including man. In most of these proteins the function of this toxin domain is unknown. This project aims to define the structure and function of this domain in a human protein, matrix metalloprotease 23, which has possible roles in prostate and other cancers. Our results will not only be of interest in tracing the structural and functional evolution of this toxin domain but will also provide valuable clues to its role in both the normal physiological function of matrix metalloprotease 23, as well as its potential pathological role in cancer.Read moreRead less
Zinc finger domains as scaffolds for protein engineering. While great advances have been made in pharmaceutical design and discovery, it is clear that new types of drugs are needed for the better management of a wide range of diseases (e.g. cancers, autoimmune diseases, viral infections). Many of these diseases arise from inappropriate interactions between intracellular biological macromolecules. My aim is to develop a range of novel therapeutic proteins based on naturally existing zinc-binding ....Zinc finger domains as scaffolds for protein engineering. While great advances have been made in pharmaceutical design and discovery, it is clear that new types of drugs are needed for the better management of a wide range of diseases (e.g. cancers, autoimmune diseases, viral infections). Many of these diseases arise from inappropriate interactions between intracellular biological macromolecules. My aim is to develop a range of novel therapeutic proteins based on naturally existing zinc-binding protein domains with the goal of selectively blocking these inappropriate interactions. Additionally, these engineered proteins have potential uses as biochemical tools such as to help delineate the functions of natural proteins with no known functions.Read moreRead less
The function of truncated MEK1 protein in a G2 phase cell cycle delay and in mitosis. Understanding cell proliferation. Intracellular signaling pathways controlling cell growth are often mutated in cancers and other hyperproliferative diseases.

Intracellular signaling pathways controlling cell growth are often mutated in cancers and other hyperproliferative diseases. Understanding precisely how these pathways operate and how mutations of these pathways can contribute to uncontrolled growth can readily provide new targets for preventative therapies or cures. We have identified a novel mechanism regulating one component of a well studied pathway, the MAPK pathway, and new functions for this component. The contribution of this novel component to mechanisms involved in regulating cell growth previously through to be controlled by the canonical MAPK pathway could change our understanding of the fundamental mechanisms controlling cell growth.

The proposed facility will represent world-leading technology in functional genomics and provide Australian scientists with unique opportunities to identify genes involved in a broad range of biological processes. This will contribute to fundamental knowledge in mammalian biology, and equally importantly, is likely to identify genes involved in important health problems such as cancer, inflammatory disease, brain damage and diabetes. Such genes may in turn constitute targets against which new therapies may be developed. This endeavour will contribute to national research priorities in both the health and scientific/technological development arenas.Read moreRead less
