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. 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

Summary
A fast fluorescence lifetime imaging microscope to track protein dynamics. 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.

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

The cell biology of the albumin-FcRn receptor recycling system. The aim of this project is to define the cell biology of the albumin-FcRn (neonatal Fc receptor) recycling system. FcRn is a recycling membrane receptor that selectively protects serum proteins from intracellular degradation and prolongs their half-life. We will identify the key cell types involved in this recycling pathway, identify intracellular sites of ligand and FcRn interaction, assess the contribution of the haematopoietic sy ....The cell biology of the albumin-FcRn receptor recycling system. The aim of this project is to define the cell biology of the albumin-FcRn (neonatal Fc receptor) recycling system. FcRn is a recycling membrane receptor that selectively protects serum proteins from intracellular degradation and prolongs their half-life. We will identify the key cell types involved in this recycling pathway, identify intracellular sites of ligand and FcRn interaction, assess the contribution of the haematopoietic system and determine ligand half-life in mice. Findings generated will reveal the basic biology of an important physiological receptor, and enable the exploitation of FcRn-receptor interactions for design of recombinant albumin fusion-based therapies.Read moreRead less
