The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a funct ....The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a functional, signalling role. The research will determine how these fibrils form and how the structures confers biological function. It could identify features in these fibrils that can be targeted as a means of ultimately preventing tissue damage after heart attack and stroke.Read moreRead less
Inhibiting protein-protein interactions involved in neural development and disease. This project will determine the molecular mechanisms by which the protein LMO4 (a regulator of brain development) binds to DEAF1 (which also regulates neural development) and CtIP (which protects against tumour formation). This will allow a set of reagents to be developed to help determine the functions of LMO4, and may ultimately be used to treat disease.

This project seeks molecular understanding of regulatory mechanisms responsible for inducing formation of specialized plant cells that are of central importance in controlling nutrient transport. These so-called "transfer cells" play pivotal roles in determining crop nutrition and hence yield under normal and stressful environments such as soil nutrient deficiencies and salinity. Discovering regulatory mechanisms that control formation of these specialized cells will maintain Australia's international reputation in this field of research. In addition, the information platform generated may provide technological opportunities to optimise nutrient flows in healthy plants, combat certain environmental stresses and control pathogen attack.

Mapping networks governing cell state plasticity: how, where and when? Single cell organisms are the basic unit of life, yet, if they had not developed the ability to change cell states we would not exist today. Changing cell states lies at the core of almost every developmental and disease process in multicellular organisms. Building upon our fundamental discovery that stem cells and non-stem cells readily interconvert, we will now incorporate innovative cell systems and the development of our ....Mapping networks governing cell state plasticity: how, where and when? Single cell organisms are the basic unit of life, yet, if they had not developed the ability to change cell states we would not exist today. Changing cell states lies at the core of almost every developmental and disease process in multicellular organisms. Building upon our fundamental discovery that stem cells and non-stem cells readily interconvert, we will now incorporate innovative cell systems and the development of our new multi-layered systems biology strategy to elucidate the first comprehensive understanding of the cell biology that underlies cell state changes. These studies are a major step toward understanding the fundamentals of life. Read moreRead less
Understanding the potency and role of individual stem cells in the skin using Rainbow technology. To renew itself, the skin and its components rely on the activity of stem cells. This project will define more precisely the role of each individual stem cell by labelling them with a unique colour and following its fate. This project has the potential to change our current view on how the skin maintains and repairs itself.
The function of small ribonucleic acid derived from the 5´ end of transfer ribonucleic acid (5´tRFs) in the regulation of gene expression and the control of the cell cycle. Small regulatory ribonucleic acid (RNAs) are key regulators of gene expression. The numbers of identified small RNAs are increasing, however the exact functions of many of these RNAs are not known. This project aims to describe the function of a small RNA which may play a role in suppressing uncontrolled cell division.

Gamete-specific knockout of Fizzy-Related to examine its meiotic role in oocytes and sperm. Fizzy-Related is a gene that appears to be essential in making an ovulated egg, and it may also have an important role to play in making sperm. A mouse knockout will be generated to examine exactly how it functions; because it affects the egg number remaining in the ovary and egg quality Fizzy-Related may be eventually an important therapeutic target.
