The role of copper in the early ubiquitination pathway. This project aims to explore the role of copper in ageing and protein turnover. The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system.

The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system. It proposes to characterise the structure and function of a newly identified copper-dependent form of cell enzyme which could be involved in amplifying ubiquitin-tagged protein breakdown. Copper is essential for life in all domains. Identifying copper as a major regulator in protein clearance is important in understanding this fundamental biological machinery.Read moreRead less

Summary
Enhancement of light-driven electricity generation by cyanobacteria: en route to biosolar panels. Some species of naturally occurring cyanobacteria (blue-green algae) exhibit a special metabolic feature, which enables them to convert sunlight into electricity. This project will unveil the chemical and biological secrets behind this process and will lead to the creation of the first entirely biological solar panel.
Deciphering new regulators of lipid metabolism: a focus on lipid droplets . Lipid droplets store lipids in cells and the mitochondria break down this lipid to generate energy. Both organelles are critical for energy metabolism and cell survival. This project aims to determine the proteins that regulate the interaction between mitochondria and lipid droplets, and how these proteins regulate metabolism.

Tracking DNA repair dynamics in the nuclear landscape of a living cell. This project aims to track DNA repair factor recruitment in the nuclear landscape of a living cell and quantify the role of nucleus architecture in maintenance of genome integrity. By coupling advanced fluorescence microscopy with a novel DNA double strand break inducible cell system, this project expects to uncover how the nucleus spatially coordinates DNA damage detection, assessment and repair in real time.

By coupling advanced fluorescence microscopy with a novel DNA double strand break inducible cell system, this project expects to uncover how the nucleus spatially coordinates DNA damage detection, assessment and repair in real time. This research is important because DNA damage threatens organism survival and this project has the potential to define how this genomic threat is resolved at the single molecule level. The benefit of this research is a fundamental insight into DNA repair biology and development of imaging technology to quantify genome function.Read moreRead less

This project aims to establish a fast fluorescence lifetime imaging microscope that can track the intracellular journey of a protein throughout the entire structural framework of a living cell. By coupling single particle tracking technology with a cutting-edge fluorescence lifetime camera, this one-of-a-kind microscope will enable protein mobility and interaction to be spatially mapped with unprecedented temporal resolution. The benefit of this technology is that it will enable scientists in Australia to image, for the first time, the biophysical mechanism by which a protein navigates intracellular architecture to regulate a complex biological function at the single molecule level.Read moreRead less
