Structure and dynamics of a multiprotein-mRNA complex involved in the regulation of gene expression. RNA/protein interactions are now recognised as a major control point in the regulation of gene-expression. Proteins such as HuR and the poly(C)-binding proteins (PCBPs) act to stabilise and transport specific messenger (m)RNAs, and thus determine their translation levels. In contrast to such an important function, very little is known about these protein/mRNA interactions at an atomic level.

RNA/protein interactions are now recognised as a major control point in the regulation of gene-expression. Proteins such as HuR and the poly(C)-binding proteins (PCBPs) act to stabilise and transport specific messenger (m)RNAs, and thus determine their translation levels. In contrast to such an important function, very little is known about these protein/mRNA interactions at an atomic level. The current study will investigate the structural and biophysical properties of a recently discovered HuR/PCBP/mRNA complex implicated in the regulation of androgen receptor expression. This information has the potential to assist in the development of drugs to reduce AR expression in prostate cancer.Read moreRead less

In the current era of 'the genome' there is more demand than ever before for the characterisation of the gene products - the oligonucleotides and proteins that carry out the important functions in the cell. The current proposal is to acquire a suite of instrumentation to characterise the kinetics, thermodynamics and overall affinities of interactions between biological macromolecules and their physiological binding partners or with novel ligands. This will reveal the role of the macromolecules of interest in the cell, and potentially lead to the discovery of drug molecules which could interfere with molecular interactions underlying disease.Read moreRead less

Acquisition of multidimensional fractionation equipment will allow researchers to separate proteins from complex mixtures, and to compare whole protein profiles of multiple samples. This will permit correlation of specific protein changes associated with infection or disease, a major focus of post-genomic programs of research. The equipment will also provide identification of the key differentiating proteins using minimal material. Numerous world-class projects and researchers will be able to move more rapidly and reliably from crude cell extracts to identifiable markers, and maintain their competitive positions the recognition of key targets in drug design, disease diagnosis and vaccine development.Read moreRead less
Protein-protein interactions in amyloid deposits. The aggregation of specific proteins to form insoluble amyloid fibrils is characteristic of several age-related diseases such as type-II diabetes, Alzheimer's disease and Parkinson's disease. In vivo amyloid deposits also contain three prominent non-fibrillar protein components, namely serum amyloid P component, apolipoprotein E and alpha1-antichymotrypsin. These non-fibrillar amyloid components bind to a wide variety of amyloid fibrils, irresp ....Protein-protein interactions in amyloid deposits. The aggregation of specific proteins to form insoluble amyloid fibrils is characteristic of several age-related diseases such as type-II diabetes, Alzheimer's disease and Parkinson's disease. In vivo amyloid deposits also contain three prominent non-fibrillar protein components, namely serum amyloid P component, apolipoprotein E and alpha1-antichymotrypsin. These non-fibrillar amyloid components bind to a wide variety of amyloid fibrils, irrespective of the nature of the protein constituent. This proposal is to identify the structural basis for this recognition process, the capacity of non-fibrillar components to cross-link amyloid fibrils to form networks and the influence of these interactions on amyloid fibril cytotoxicity.Read moreRead less

This project will develop and use novel neutron and x-ray scattering methods to study the molecular mechanisms by which nature regulates biochemical processes. Healthy function requires cells to tightly control and coordinate a myriad of molecular activities. My research focuses on a set of interdependent molecular networks inside cells whose behavior is controlled by the so-called 'second messengers' that translate external signals into the right cellular responses. The proposed experiments will provide a unique structural framework by which we can understand how these signals are transmitted. Such knowledge is an important foundation for advances in biomedical research and biotechnology applications.Read moreRead less
