Summary
The spread of cancer to other parts of the body (metastasis) is a major cause of mortality. The characterisation of proteins that regulate metastasis is therefore a priority. P-Rex1 plays a crucial role in promoting metastasis in breast and other cancers. We will determine the structural basis of P-Rex1 activity, and investigate how its dysregulation promotes aberrant cell growth. This study will provide the knowledge to build future drug development programs targeting P-Rex1 in cancer.
Structural Characterisation Of Long Non-Coding RNA Bound Histone Modification Complexes

Funding Amount
$320,891.00
Summary
Cancer is a disease associated with genetic and epigenetic changes of DNA. Epigenetics involves external changes to the DNA, switching processes “on” and “off”, to regulate gene expression. This project aims to provide powerful insight into key processes involved in epigenetic-based carcinogenesis, and thereby lay the foundation for producing novel cancer diagnostic markers and molecular based therapies.
Characterisation Of TIA Proteins In RNA Recognition And Stress Granule Formation

Funding Amount
$566,966.00
Summary
Cells in our body need to be able to respond to stresses such as heat, hypoxia, chemical stress or infection. In this project we investigate the specialized TIA proteins that have the job of protecting RNA in stressed cells. We will investigate the way TIA proteins recognize particular mRNA and form temporary protective clusters. By better understanding this process we will gain insight into the way in which cells are susceptible to damage in diseases including neurodegenerative disease.
Molecular Basis For RIG-I Like Receptor Activation Of The Innate Immune Pathway.

Funding Amount
$564,770.00
Summary
This project is to understand how proteins in the cell detect the presence of invading viruses, and pass on the message for the cell to produce defence molecules. The overproduction of these defence molecules can lead to inflammatory diseases. This research will help us to understand the process of the innate immune response in cells and how we might control it in disease states.
DBHS Protein RNA Interactions In Health And Disease

Funding Amount
$748,073.00
Summary
In cells involved in cancer, the interactions of DBHS proteins with each other, and with nucleic acids (eg RNA) are different to those in healthy cells. Only once we understand how DBHS proteins interact with some important RNA molecules, and how these interactions affect cell biology, can we begin to open up new pathways for therapy. This proposal aims at understanding and explaining this complex aspect of biology.
Mechanisms Of Gene Regulation - Structure, Function And Design
Funder

Funding Amount
$697,209.00
Summary
The human genome contains at least 20000 genes. The activity of these genes must be tightly controlled throughout an individual’s life and problems with the regulation of genes lie at the heart of many common and serious diseases, including most forms of cancer. My program of research is focused on understanding the mechanisms underlying gene regulation and on the design of new reagents that could be used to manipulate the activity of genes that behave aberrantly in disease states.
Modulation Of Gene Regulation By DBHS Protein Interactions

Funding Amount
$443,244.00
Summary
The DBHS family of proteins have been shown to affect, in a novel manner, the way human cells control which genes are made into proteins - a fundamental process in healthy and cancerous cells. This project will employ cutting edge structural, molecular and cellular techniques to determine how these protein molecules interact with each other and with important gene regulatory proteins to determine cell fate.
A new source of bivalent molecules from nature. This project aims to describe a new class of naturally occurring multivalent molecules termed secreted cysteine-rich repeat proteins (SCREPs). Multivalency is a key feature of molecular interaction in biology, underlying the high specificity and potency found in many proteins. Focusing on bivalent peptides, the project will generate a database of bioactive SCREPs with similarity to known bioactive peptides, and develop new recombinant methods for t ....A new source of bivalent molecules from nature. This project aims to describe a new class of naturally occurring multivalent molecules termed secreted cysteine-rich repeat proteins (SCREPs).

Focusing on bivalent peptides, the project will generate a database of bioactive SCREPs with similarity to known bioactive peptides, and develop new recombinant methods for their production. The project will use advanced nuclear magnetic resonance spectroscopy to characterise members of this new class, providing new insights into the design of bivalent and multivalent peptides and establishing a new source of molecules with applications in the rapidly growing biotechnology sector.Read moreRead less

The project will focus on the sliding clamp subunit of the bacterial replicative polymerase by studying its association with many other proteins in vitro and in vivo, using novel techniques in solid-state NMR, single-molecule fluorescence and molecular microbiology. The outcomes are expected to be an increased understanding of bacterial DNA replication and mechanisms of antibiotic action and resistance. This project expects to generate new knowledge to assist in combatting antibiotic resistance in Gram-negative bacterial pathogens.Read moreRead less
