Current techniques for membrane protein are inadequate for the emerging proteomic challenge, in which approximately 40% of proteins are predicted to be membrane associated. The aim of this proposal is to develop a new approach to purify membrane proteins using our recently-developed immobilised membrane chromatography materials. The present proposal will provide a new high-resolution separation technique that allows isolation and on-line mass analysis of complex mixtures of membrane proteins for subsequent proteomic analysis, high-throughput screening or structural studies and could form the basis for further development of new commercial tools for membrane protein analysis.Read moreRead less

The design and synthesis of angiotensin converting enzyme-2 (ACE2) inhibitors. A vast number of current drugs on the market are inhibitors of enzymes whose action needs to be controlled in order to treat many conditions. This proposal will apply our new approaches to the design of enzyme inhibitors with superior therapeutic action. The benefits of this research reside in new treatments for a range of cardiovascular diseases (the 3rd largest cause of mortality in Australia) and provide a platform ....The design and synthesis of angiotensin converting enzyme-2 (ACE2) inhibitors.

Structural studies on the mitochondrial protein import machinery. Proteins transported across biological membranes are generally synthesized as precursors with signal sequences. These signal sequences are decoded by one of a number of membrane-specific protein transport machinery, but how this decoding occurs is largely unknown. This proposal aims to understand the structural basis of protein import into the mitochondrion, a poorly understood biological process. This study will enhance signif ....Structural studies on the mitochondrial protein import machinery. Proteins transported across biological membranes are generally synthesized as precursors with signal sequences. These signal sequences are decoded by one of a number of membrane-specific protein transport machinery, but how this decoding occurs is largely unknown. This proposal aims to understand the structural basis of protein import into the mitochondrion, a poorly understood biological process. This study will enhance significantly our understanding of mitochondrial biology, and will also have ramifications for other areas of protein transport.Read moreRead less
Guanylate cyclases - an expanding family critical in plant growth and development. The enzyme guanylate cyclase (GC) forms an important signalling molecule. We have identified unique GC molecules from higher plants. We shall use strategic basic research to determine the biological importance of these novel molecules in plant growth and development.

Analysis of the Role of Snapin in the Regulation of SNARE Complex Assembly. The aims of the proposed studies are to investigate the role played by a protein, snapin in the trafficking of membranes and cargo proteins between different compartments inside mammalian cells.

The aims of the proposed studies are to investigate the role played by a protein, snapin in the trafficking of membranes and cargo proteins between different compartments inside mammalian cells. Membrane trafficking is a fundamental cellular process that requires a family of related molecules termed SNARES. We have recently discovered that snapin interacts with certain members of the SNARE family, implying a critical role in membrane trafficking. The proposed studies will provide important new insights into the molecular mechanisms underlying the function of both snapin and SNAREs, and membrane trafficking in general.Read moreRead less
