Summary
The molecular mechanisms of dual nucleic acid specificities of SFPQ. Dynamic interactions between proteins and nucleic acids are a fundamental process in gene regulation, where aberrant regulation leads to lethality or various diseases. This project aims to elucidate the underlying mechanisms of DNA-RNA interplay with a multifunctional nuclear protein, splicing factor proline/glutamine-rich (SFPQ) in gene regulation at the molecular level by characterising the interactions between SFPQ and nucle ....The molecular mechanisms of dual nucleic acid specificities of SFPQ. Dynamic interactions between proteins and nucleic acids are a fundamental process in gene regulation, where aberrant regulation leads to lethality or various diseases. This project aims to elucidate the underlying mechanisms of DNA-RNA interplay with a multifunctional nuclear protein, splicing factor proline/glutamine-rich (SFPQ) in gene regulation at the molecular level by characterising the interactions between SFPQ and nucleic acids. The results will provide a fundamental understanding of the molecular mechanisms of dual nucleic acid specificities of nuclear proteins in gene regulation, for which no structural information is currently available.Read moreRead less
The early structural assembly of high-density lipoproteins. This project aims to study the interaction between proteins and lipids, a fundamental aspect of cellular processes in all organisms. Lipid binding by apoA-I forms high-density lipoproteins (HDL) in the bloodstream, which removes cholesterol from the body. This project will define the types of lipids that bind first to the apolipoprotein (apo) A-I and the structural mechanisms of this process. The conformation of lipid binding proteins o ....The early structural assembly of high-density lipoproteins. This project aims to study the interaction between proteins and lipids, a fundamental aspect of cellular processes in all organisms. Lipid binding by apoA-I forms high-density lipoproteins (HDL) in the bloodstream, which removes cholesterol from the body. This project will define the types of lipids that bind first to the apolipoprotein (apo) A-I and the structural mechanisms of this process. The conformation of lipid binding proteins often changes during lipid binding. However, the structural mechanisms and conformational rearrangements are poorly understood. This project expects to understand the function of HDL and the structural mechanisms of lipid binding proteins in general. The results will have far-reaching applications in biology, human health, and biotechnology, including food and biopharmaceutical processing.Read moreRead less

This proposal will address a major gap in our mass spectrometry capabilities and aid in our understanding of protein interactions and tissue distribution in areas such as neuroscience, microbiology, immunology, and botany, as well as enhance our understanding of fundamental gas phase chemistry of protein molecules. It brings together a highly successful multidisciplinary team of high-profile researchers with a track record of collaboration and delivering outcomes from shared facilities. In addition to these key scientific outcomes this project will also facilitate the training of several new personnel in a skill area for which there is a critical shortage (mass spectrometry) and promote true cross-disciplinary skills.Read moreRead less
Deciphering the cellular defences against aggregating proteins in human disease. Cells have inbuilt defences for coping with proteins that bend into abnormal sticky shapes that form toxic clusters. In many diseases, including Huntington's, the clusters severely damage nerve cells. This project will identify the genes and mechanisms cells use to protect themselves from toxic clusters, which could provide new therapeutic targets.

Proteins are highly dynamic molecules that are essential to life. This project aims to acquire a fully automated and integrated hydrogen-deuterium exchange system, a powerful tool for analysing the motion of proteins and their interactions with other molecules. Expected outcomes include a new capability for biology labs around Australia by (1) increasing success rates of difficult projects that aim to visualise 3D protein structures and (2) providing rapid information about protein interaction sites. Anticipated benefits include the generation of dynamic data that will be highly complementary to static pictures of protein structures. This will enable clever design of new proteins with beneficial uses in the biotechnology industry.Read moreRead less
Defining the cellular impacts of protein aggregation in neurodegenerative disease with an aggreomics platform. The brain disease Huntington’s is caused by abnormally shaped proteins that assemble into toxic clusters. This project will design new bioprobes to track how these clusters form and cause damage to cells. This strategy will also provide new opportunities for discovering novel therapeutic targets.

Identification of Proteins that Regulate Apoptosis Through Interaction With IAPS. Apoptosis is the process by which multicellular organisms eliminate unwanted cells. Identifying proteins involved in cell death regulation is central to our understanding of disease states arising from aberrations in this process.

Given the existence of several IAP regulatory proteins (IRPs ....Identification of Proteins that Regulate Apoptosis Through Interaction With IAPS. Apoptosis is the process by which multicellular organisms eliminate unwanted cells. Identifying proteins involved in cell death regulation is central to our understanding of disease states arising from aberrations in this process. The mammalian protein DIABLO, promotes cell death by interacting with and antagonising inhibitor of apoptosis proteins (IAPS). Given the existence of several IAP regulatory proteins (IRPs) in insects, other mammalian IRPs probably also exist. These may be of equal importance in regulating apoptosis, especially in tissues where DIABLO is not expressed. The main aim of the proposed study is to idenitify and characterise other IRPs in mammalian cells.Read moreRead less

Sugar polymers play key structural and functional roles in plant development and determine quality for all plant-based products including food, textile fibres, building materials and renewable biomass. However, unknown mechanisms regulate and control the transport mechanisms that deliver the building blocks for polysaccharide biosynthesis. This project is expected to increase understanding of nucleotide sugar transport and develop and enhance the biological toolbox for applications involving modelling and engineering of plants, synthesis of industrial biopolymers and production of functional foods.Read moreRead less
