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.

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. We have formed an international team to achieve these goals and also to develop strong scientific links between Australia and other countries such as ....Guanylate cyclases - an expanding family critical in plant growth and development.

Regulation of the actin cytoskeleton by LIM kinase 2. Because the regulation of actin cytoskeleton is essential for many cellular processes including cell motility and the normal function of neurons, it is of great importance to understand its regulation. Elucidation of the molecular and biological mechanisms underlying the actin cytoskeleton including cell motility may enable the identification of novel therapeutic targets for the treatment of diseases such as cancer metastasis, Alzheimer disea ....Regulation of the actin cytoskeleton by LIM kinase 2.

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. 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 rol ....Analysis of the Role of Snapin in the Regulation of SNARE Complex Assembly.

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
Continuous wave excitation for low power Magnetic Resonance Imaging. This project aims to augment the capabilities of Magnetic Resonance Imaging (MRI) systems, using continuous wave (CW) transmission and signal reception, to image objects using very low excitation power. Any given MRI sequence tries to solve an inverse problem, involving estimation of some subset of hidden states and parameters of the system, given the observed data.

This project aims to augment the capabilities of Magnetic Resonance Imaging (MRI) systems, using continuous wave (CW) transmission and signal reception, to image objects using very low excitation power. Any given MRI sequence tries to solve an inverse problem, involving estimation of some subset of hidden states and parameters of the system, given the observed data. Using transient and steady-state CW magnetisation dynamics to solve inverse problems is expected to advance technology toward lower power, lower cost solutions for MRI scanners in healthcare and industrial applications, including materials science and mineral processing.Read moreRead less
How protein tyrosine phosphatases select their substrates. Protein tyrosine phosphatases (PTPs) are enzymes that control the response of cells to divergent environmental stimuli. This project will determine how individual PTPs exert selective effects on cellular communication networks to coordinate organismal development, growth and survival.
