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

Summary
Protein Over-Expression/Purification and Macromolecular Structure Determination by X-Ray Diffraction. This proposal seeks funds for state-of-the-art facilities for protein over-expression and macromolecular X-ray diffraction. This will build upon recent initiatives within the collaborating institutions in the field of Structural Biology. It will enable research groups in Perth to pursue the large-scale production of important proteins and to conduct high-resolution structural studies using X-ray ....Protein Over-Expression/Purification and Macromolecular Structure Determination by X-Ray Diffraction. This proposal seeks funds for state-of-the-art facilities for protein over-expression and macromolecular X-ray diffraction. This will build upon recent initiatives within the collaborating institutions in the field of Structural Biology. It will enable research groups in Perth to pursue the large-scale production of important proteins and to conduct high-resolution structural studies using X-ray crystallographic techniques. This technology, which is one of the most important tools in modern biology, provides unique insights into the chemical mechanisms of biological macromolecules and will significantly enhance a great breadth of biological research in Western Australia.Read moreRead less
Molecular machines: regulation of the catalysis and rotation of the enzyme ATP synthase. This project aims to elucidate the regulation of the molecular machine ATP synthase. ATP synthase is an enzyme that performs a critical role in all cells - the synthesis of ATP, the universal biological energy currency. It is known that the enzyme operates via rotation of a central stalk which is driven by a hydrogen ion gradient across a membrane. Constructs of this molecule have been envisaged in the desig ....Molecular machines: regulation of the catalysis and rotation of the enzyme ATP synthase. This project aims to elucidate the regulation of the molecular machine ATP synthase. ATP synthase is an enzyme that performs a critical role in all cells - the synthesis of ATP, the universal biological energy currency. It is known that the enzyme operates via rotation of a central stalk which is driven by a hydrogen ion gradient across a membrane. Constructs of this molecule have been envisaged in the design of future biological nano-motors. Our work will provide an understanding of the regulation of this enzyme with potential application in the control of nano-motors.Read moreRead less
