An Investigation of the Structure and Conformational Stability of a Membrane Associating Protein and its Petidic Ligands. The genome of the parasite most commonly responsible for fatal malaria will be completed this year. Structural elucidations of proteins identified from these genomic data will expedite the identification and classification of proteins synthesised by the parasite that might be developed as vaccines or as targets for anti-malarial therapeutics. In this work, recent developmen ....An Investigation of the Structure and Conformational Stability of a Membrane Associating Protein and its Petidic Ligands. The genome of the parasite most commonly responsible for fatal malaria will be completed this year. Structural elucidations of proteins identified from these genomic data will expedite the identification and classification of proteins synthesised by the parasite that might be developed as vaccines or as targets for anti-malarial therapeutics. In this work, recent developments in structural biology will be employed to obtain the structure of a vaccine candidate and to identify environmental factors that influence the stability of this structure. A novel approach will be taken to determine the conformation of ligands bound to such proteins, which will provide a basis for the development of therapeutics.Read moreRead less
Cell biology of gastric acid secretion. This research will result in a better understanding of the membrane structures in cells. In turn, this information could be exploited to manipulate ion transport, uptake, secretion of biological molecules, signal transduction events and the delivery and uptake of drugs in a number of disease situations thus leading to more effective therapies.
Furthermore, this work will utilise and develop state-of-the-art technologies, contributing to national competiti ....Cell biology of gastric acid secretion.

Biochemical, Genomic and Phenomic Analysis of Gastric Parietal Cells from Wildtype and Mutant Mice. The interface between the cell and its environment is the cell membrane. Signals, nutrients, and ions all have to cross this barrier. In addition, the cells contain many specialized intracellular membranous compartments. We know little about the signals that direct the synthesis of these structures and determine their final composition and shape. This grant will utilize acid secretory cells in the ....Biochemical, Genomic and Phenomic Analysis of Gastric Parietal Cells from Wildtype and Mutant Mice. The interface between the cell and its environment is the cell membrane. Signals, nutrients, and ions all have to cross this barrier. In addition, the cells contain many specialized intracellular membranous compartments. We know little about the signals that direct the synthesis of these structures and determine their final composition and shape. This grant will utilize acid secretory cells in the stomach to examine these questions because they contain a very extensive membrane system. We will use a state-of-the-art genetic and cell biological technologies to manipulate and analyse these cells in a whole animal setting.Read moreRead less
Malarial parasite surface proteins: structure and interactions of key merozoite antigens. Malaria remains one the most lethal infectious diseases in the world today, being directly responsible for around 2 million deaths annually, many in children under 5 years of age. Related parasitic diseases affect livestock in malaria-endemic regions and more broadly. There is an urgent need for an improved understanding of how these parasites invade target red blood cells. Knowing the structures of key pro ....Malarial parasite surface proteins: structure and interactions of key merozoite antigens. Malaria remains one the most lethal infectious diseases in the world today, being directly responsible for around 2 million deaths annually, many in children under 5 years of age. Related parasitic diseases affect livestock in malaria-endemic regions and more broadly. There is an urgent need for an improved understanding of how these parasites invade target red blood cells. Knowing the structures of key proteins on the parasite cell surface will provide a deeper understanding of host-parasite interactions, as well as a basis for the design of vaccines or drugs that interfere with parasite invasion of host red blood cells.
