Synthetic regulators of gene expression. RNA plays many essential roles in cells, from information transfer and regulation of gene expression to scaffolding macromolecular structures and catalysis. Despite these realisations the current approaches to manipulate RNA are limited in many respects. This project will use synthetic biology approaches to engineer synthetic regulators of RNAs in living cells. These studies will provide new tools for use in biological research and provide insights into h ....Synthetic regulators of gene expression. RNA plays many essential roles in cells, from information transfer and regulation of gene expression to scaffolding macromolecular structures and catalysis. Despite these realisations the current approaches to manipulate RNA are limited in many respects. This project will use synthetic biology approaches to engineer synthetic regulators of RNAs in living cells. These studies will provide new tools for use in biological research and provide insights into how natural proteins control gene expression. Furthermore, this project will use these tools to understand the mechanisms of how proteins are synthesised in mammalian mitochondria.Read moreRead less
Protein Kinase Regulatory Switches: Decision-Making in the Nucleus. This project plans to examine new regulatory mechanisms for an important signalling enzyme in the cell nucleus. It aims to define how this enzyme enters the nucleus, to characterise new modifications that affect its actions, and to establish how a conserved nuclear protein may provide an unexpected regulatory platform to send nucleus-initiated signals back to the cell cytoplasm. This reverse signalling is a novel mechanism for i ....Protein Kinase Regulatory Switches: Decision-Making in the Nucleus. This project plans to examine new regulatory mechanisms for an important signalling enzyme in the cell nucleus. It aims to define how this enzyme enters the nucleus, to characterise new modifications that affect its actions, and to establish how a conserved nuclear protein may provide an unexpected regulatory platform to send nucleus-initiated signals back to the cell cytoplasm. This reverse signalling is a novel mechanism for integrating nuclear actions that has the potential to create a signal transduction circuit triggered by environmental or genetic factors. This information is crucial in defining the molecular logic of signalling events that may be ultimately targeted to control cell growth, differentiation and survival.Read moreRead less
Signal transduction and the control of bacterial respiration by the NtrYX two component regulatory system. This proposal will define the structural and functional properties of the NtrYX two component signal transduction and define its role in the regulation of respiratory gene expression. The human pathogen Neisseria gonorrhoeae will be used as a model organism for a diverse range of 'oxidase positive' bacteria that possess NtrYX. The outcome will be a major contribution to the understanding of ....Signal transduction and the control of bacterial respiration by the NtrYX two component regulatory system. This proposal will define the structural and functional properties of the NtrYX two component signal transduction and define its role in the regulation of respiratory gene expression. The human pathogen Neisseria gonorrhoeae will be used as a model organism for a diverse range of 'oxidase positive' bacteria that possess NtrYX. The outcome will be a major contribution to the understanding of way in which respiratory gene expression is controlled in bacterial species for which Escherichia coli is not a suitable model.

The selective elimination of mitochondria from yeast cells: regulation and molecular mechanism . For healthy cells the quality of the mitochondrion, the cellular power plant, must be maintained. The results of this research will contribute to an understanding of the molecular mechanism for the removal of mitochondria from the cell, and ultimately inspire strategies for the treatment of diseases that result from faulty mitochondria.

Summary
Identifying molecular regulators of haematopoietic stem cell development. Blood stem cells are capable of making all types of mature blood cell whilst making new copies of themselves. These properties are essential for the life-long supply of blood and make stem cells ideal for therapeutic use. By studying embryos, this project will identify genes that control the production and expansion of blood-forming stem cells.
The Hippo signalling pathway in dividing and non-dividing cells. This project aims to understand how the Drosophila Hippo pathway performs two very different jobs in the same organ, that is control cell proliferation and differentiation. The redeployment of cellular machinery to do different jobs is very common and efficient, but the mechanism by which this occurs is poorly understood. Using new techniques, this project aims to provide new knowledge to several fields including organ growth contr ....The Hippo signalling pathway in dividing and non-dividing cells. This project aims to understand how the Drosophila Hippo pathway performs two very different jobs in the same organ, that is control cell proliferation and differentiation. The redeployment of cellular machinery to do different jobs is very common and efficient, but the mechanism by which this occurs is poorly understood. Using new techniques, this project aims to provide new knowledge to several fields including organ growth control, cell fate specification, cellular signalling and eye vision. These discoveries are likely to enhance international collaborations and stimulate new research.Read moreRead less
How protein and RNA cargo are sorted into exosomes. This project aims to understand how proteins and RNA are selected for packaging into exosomes and participate in the biological functions mediated by these vesicles. Exosomes are small membranous extracellular vesicles released by cells which contain protein and RNA cargo and are involved in intercellular communication. Determining how the exosome cargo is selected and related to its function in intercellular communication is expected to show h ....How protein and RNA cargo are sorted into exosomes. This project aims to understand how proteins and RNA are selected for packaging into exosomes and participate in the biological functions mediated by these vesicles. Exosomes are small membranous extracellular vesicles released by cells which contain protein and RNA cargo and are involved in intercellular communication. Determining how the exosome cargo is selected and related to its function in intercellular communication is expected to show how these vesicles maintain cellular homeostasis. The findings will expand knowledge in the area of microRNA biology, proteomics and develop expertise in bioinformatics.Read moreRead less
Transcription factor nuclear residency as a driver of gene expression. Persistently active proteins can stay in the nucleus to drive cell growth and prevent cell death. This project will define how one specific active protein can remain in the nucleus and regulate gene expression through the action of unique ribonucleic acid (RNA) molecules. The results will enable persistent gene activation to be manipulated in cancer.

Physiology and genetics of barley grain germination in the malting and brewing industries. An international research team will provide new scientific information on barley grain germination. This detailed basic knowledge will be immediately applied in breeding programs that are aimed at improving malting and brewing quality in a commercial context. At the same time, the industry's carbon footprint will be significantly reduced.
