The role of HP1 alpha dimerisation in maintaining chromatin structure. Heterochromatin protein 1 alpha (HP1a) is an architectural protein that decorates three-dimensional genome organisation and through self-association into HP1a dimers regulates global gene expression. While there is extensive biochemical evidence on how HP1a molecules bind DNA, dimerise and bridge nucleosomes close together, we still do not know how HP1a regulates higher order chromatin structure in the context of a living cel ....The role of HP1 alpha dimerisation in maintaining chromatin structure. Heterochromatin protein 1 alpha (HP1a) is an architectural protein that decorates three-dimensional genome organisation and through self-association into HP1a dimers regulates global gene expression. While there is extensive biochemical evidence on how HP1a molecules bind DNA, dimerise and bridge nucleosomes close together, we still do not know how HP1a regulates higher order chromatin structure in the context of a living cell. Thus, by use of cutting-edge fluorescence microscopy methods, the overall aim of this research project is to determine the biophysical mechanism by which the HP1a monomer to dimer transition spatially and temporally modulates live cell chromatin network organisation to ensure faithful transmission of the genome.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. 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 resolut ....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. 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
Decoding the spatiotemporal control of DNA replication and repair. DNA replication is the fundamental mechanism of genetic inheritance and essential for all cellular life. This project aims to inform our understanding of how human cells coordinate the DNA replication machinery in time and space to accurately copy the human genome. By applying multiple innovative approaches and employing an interdisciplinary research team, this project is anticipated to generate new knowledge that explains how th ....Decoding the spatiotemporal control of DNA replication and repair. DNA replication is the fundamental mechanism of genetic inheritance and essential for all cellular life. This project aims to inform our understanding of how human cells coordinate the DNA replication machinery in time and space to accurately copy the human genome. By applying multiple innovative approaches and employing an interdisciplinary research team, this project is anticipated to generate new knowledge that explains how the human genome is replicated. This knowledge is expected to generate research publications of high quality and provide economic benefits, such as unlocking new potentially patentable DNA technologies. Read moreRead less
