How neurons maintain their fate. This project aims to investigate how neurons maintain their identity, without reverting back to less specialised cells. Stable fate maintenance is essential because when it fails, cells lose their ability to perform their ascribed function, which impedes organism fitness. This project aims to define how two proteins work in partnership to maintain the identity of brain neurons. We intend our discoveries to stimulate new research, for example to test whether the h ....How neurons maintain their fate. This project aims to investigate how neurons maintain their identity, without reverting back to less specialised cells. Stable fate maintenance is essential because when it fails, cells lose their ability to perform their ascribed function, which impedes organism fitness. This project aims to define how two proteins work in partnership to maintain the identity of brain neurons. We intend our discoveries to stimulate new research, for example to test whether the human counterparts of the Drosophila proteins studied here, function similarly. Benefits will be provided in the form of job creation, and new knowledge in fundamental aspects of life, including brain development and cell fate maintenance.Read moreRead less
Decoding miRNA regulated genetic circuits. This project will aim to develop a much better understanding of how the process of making proteins from genes is regulated, and will develop scientific software capable of predicting how a cell will respond to changes in this regulation. The results will have widespread use, including assistance in deciding the best treatments for genetic diseases.
Regulation of histone methylation by polycomb-like proteins. This project aims to investigate how polycomb-like proteins regulate polycomb group (PcG) proteins and recruit them to their target genes. During the development of all multicellular organisms, PcG proteins are essential for keeping thousands of genes in a repressed state. PcG proteins are recruited to their target genes with the aid of their Polycomb-like protein cofactors, in a process that is poorly understood mechanistically. This ....Regulation of histone methylation by polycomb-like proteins. This project aims to investigate how polycomb-like proteins regulate polycomb group (PcG) proteins and recruit them to their target genes. During the development of all multicellular organisms, PcG proteins are essential for keeping thousands of genes in a repressed state. PcG proteins are recruited to their target genes with the aid of their Polycomb-like protein cofactors, in a process that is poorly understood mechanistically. This project will determine the mechanism that underpins the recruitment and regulation of PcG proteins by polycomb-like proteins. Outcomes will have relevance for most development processes of multicellular organisms.Read moreRead less
Engineering a chromatin looping factor for artificial gene regulation. This project aims to define mechanisms of chromatin looping and gene activation by a widely expressed mammalian protein. The project will establish if the functions of this protein are modulated by the binding of small molecules, whether it can act in conjunction with closely related proteins, and if post-translational modifications regulate looping and gene activation. Using protein engineering the project will develop synth ....Engineering a chromatin looping factor for artificial gene regulation. This project aims to define mechanisms of chromatin looping and gene activation by a widely expressed mammalian protein. The project will establish if the functions of this protein are modulated by the binding of small molecules, whether it can act in conjunction with closely related proteins, and if post-translational modifications regulate looping and gene activation. Using protein engineering the project will develop synthetic looping factors that can switch on a wide array of target genes. The project aims to answer fundamental questions about how proteins can establish and maintain physical loops in DNA to modulate gene expression. The project will also develop research tools that might ultimately correct diseases caused by the faulty expression of genes.Read moreRead less
The role of phosphoinositides in endosomal maturation dynamics. This project aims to investigate the regulation of an intracellular compartment within a cell called endosomes, which plays critical roles in cellular homeostasis, signalling and pathogen entry. New knowledge is expected to be generated in understanding endosome maturation and the signalling events that drive this process using a unique, multidisciplinary approach combining state of the art imaging techniques and high throughput pro ....The role of phosphoinositides in endosomal maturation dynamics. This project aims to investigate the regulation of an intracellular compartment within a cell called endosomes, which plays critical roles in cellular homeostasis, signalling and pathogen entry. New knowledge is expected to be generated in understanding endosome maturation and the signalling events that drive this process using a unique, multidisciplinary approach combining state of the art imaging techniques and high throughput protein analysis. The anticipated outcomes will be to define the molecular steps that govern the membrane-bound machinery on endosomes that directs endosomal maturation. This should provide significant benefits in delineating a process that is linked to almost all aspects of cell life.Read moreRead less

This project aims to develop novel bioinformatics methods for single cell transcriptomic data that seek to model variability in cell populations. The project expects to generate new approaches using Bayesian statistics that will act as high-end enablers of discovery in transcriptional regulatory processes. Through an interdisciplinary combination of experimental and computational research, insights into fundamental biological processes will be elucidated, specifically the robustness of cellular systems. Expected outcomes include a suite of novel tools that will push the boundaries of current bioinformatics solutions with potential to deliver significant benefits to every domain of biological science, particularly tissue engineering and synthetic biology.Read moreRead less
Organising Intracellular Compartments by Formation of Transport Carriers. This project aims to investigate the cellular components which generate carriers that transport material between compartments within the cell. The process of sorting proteins and sending them to the right place is a fundamental mechanism critical to understand how individual proteins function as the move around within cells.

This project aims to investigate the cellular components which generate carriers that transport material between compartments within the cell. The process of sorting proteins and sending them to the right place is a fundamental mechanism critical to understand how individual proteins function as the move around within cells. The generated knowledge about how cells organise themselves through the movement of proteins between endosomal intracellular compartments will provide significant benefits by enhancing our capacity to understand this conserved cellular pathway which ensures the integrity of all cellular processes including signalling, communication, homeostasis and development.Read moreRead less

Understanding how cells function in the ‘real-time’ context of a living organism is a key challenge in the new era of cell biology. Using super-resolution light microscopy and state-of-the-art correlative electron microscopy together with model systems, this Fellowship aims to deliver new understandings of cells in their natural environment. Significantly, the project will elucidate how proteins or nanoparticles pass from the bloodstream into tissues and then into cells, and in doing so deliver much-needed knowledge of protein and particle trafficking in situ. Outcomes and benefits include leading-edge fundamental science into the function of cells, education, outreach and building of Australian capacity in high-demand skill sets.Read moreRead less

Neurons communicate via synapses, where chemicals (such as glutamate) are released to transmit neuronal signals. This proposal is aimed at understanding the molecular mechanisms of neuronal communication and adaptive plasticity, which are essential for normal brain function. The proposed research will combine biophysical, biochemical, molecular and cell biological assays to elucidate the role of a calcium binding protein in controlling glutamate receptor trafficking in neurons. The outcomes will enhance our understanding of how neural plasticity is generated and maintained, knowledge that is critical for our understanding of cellular correlates of information, sensory and motor processing, as well as learning, memory and cognition.
