Summary
A cellular nano-imaging facility: Probing cellular complexity. Answering the major medical and biotechnology questions of the 21st century will be heavily reliant on the use of advanced imaging techniques. This facility will establish a new and revolutionary microscope which is capable of producing images of living cells in action at high magnification and with the greatest clarity.
Expression and substrate recognition by MARCH ubiquitin ligases. Eukaryotic cells are compartmentalised, with different organelles playing distinct functions. This project will characterise the MARCHs, proteins which control the localisation and half-life of other proteins. Understanding how the MARCHs work will provide novel insights into fundamental cellular processes that play major roles in many biological functions.
Breaking through the Gram-negative cell barrier. This project aims to develop fundamental knowledge of the cell envelope in Gram-negative bacteria, which functions as a permeability barrier to small molecules. Combining innovative functional genomics with biochemistry, this project will determine how small molecules can pass across the cell envelope, and the chemical properties that they need to do so. Some Gram-negative bacteria are human pathogens and cause serious infections, whereas others a ....Breaking through the Gram-negative cell barrier. This project aims to develop fundamental knowledge of the cell envelope in Gram-negative bacteria, which functions as a permeability barrier to small molecules. Combining innovative functional genomics with biochemistry, this project will determine how small molecules can pass across the cell envelope, and the chemical properties that they need to do so. Some Gram-negative bacteria are human pathogens and cause serious infections, whereas others are used in biotechnology for biosynthetic chemical production or bioremediation. This project expects to help the future development of new antibiotics and assist in the design of strains to be used in biotechnological applications.Read moreRead less

The project aims to establish a high throughput protein nanocrystallisation and imaging facility for protein crystallography. Protein crystallography is an important field of biological research, however there are many proteins, such as integral membrane proteins and transient molecular complexes that are more challenging to crystallise. The facility aims to use state-of-the-art imaging and crystallisation techniques, including second order nonlinear imaging of chiral crystals (SONICC) imaging and lipid cubic phase approaches, to enable structural studies to be undertaken on challenging proteins. This information is often used for the rational development of therapeutics. The facility would support cutting-edge biological research In Australia.Read moreRead less

Summary
Exploiting pathogen-host interactions to dissect the mammalian endocytic pathway. Salmonella manipulates the cells of the human body to cause disease. Understanding the molecular machinery that controls this process will provide profound insight into how the bacteria orchestrates this manipulation as well as provide possible avenues for intervention and even cures for diseases like typhoid fever.

Summary
Export of effector proteins by P. falciparum to the infected red blood cell. Infection by the malaria parasite has lethal consequences for humans. The parasite exports hundreds of proteins via a translocon to commandeer the red blood cell. This project aims to determine the function of one of the major translocon components and determine if it is a viable target for anti-malarial drug development.

Ion regulation in Apicomplexan parasites. This project aims to determine how Apicomplexan parasites regulate their sodium and chloride levels to support the development of new parasite control measures. Apicomplexan parasites cause devastating animal and human diseases. Little is known about the physiology of these parasites, and options for controlling them are few. Apicomplexan parasites must precisely control their internal ion compositions in order to survive, but how they do so is not under ....Ion regulation in Apicomplexan parasites. This project aims to determine how Apicomplexan parasites regulate their sodium and chloride levels to support the development of new parasite control measures. Apicomplexan parasites cause devastating animal and human diseases. Little is known about the physiology of these parasites, and options for controlling them are few. Apicomplexan parasites must precisely control their internal ion compositions in order to survive, but how they do so is not understood. Recent work has identified a unique Apicomplexan sodium transporter and revealed a number of chloride transporter candidates. Using a combination of molecular biology and physiological techniques, this project aims to characterise the Apicomplexan sodium transporter in detail and elucidate the molecular mechanisms of chloride transport.Read moreRead less
Regulating nutrient uptake in intracellular parasites. Parasites impose a major economic and medical burden on human societies. In order to grow and reproduce, parasites scavenge nutrients from their animal or human hosts. As they move within and between hosts they encounter different levels of nutrients; how they adapt to these differences is poorly understood. This project aims to investigate the mechanisms by which the model parasite Toxoplasma senses and responds to the nutrients in its envi ....Regulating nutrient uptake in intracellular parasites. Parasites impose a major economic and medical burden on human societies. In order to grow and reproduce, parasites scavenge nutrients from their animal or human hosts. As they move within and between hosts they encounter different levels of nutrients; how they adapt to these differences is poorly understood. This project aims to investigate the mechanisms by which the model parasite Toxoplasma senses and responds to the nutrients in its environment, thereby shedding light on how they adapt to the different environments that they inhabit and, in the longer term, informing novel treatment strategies that aim to limit the parasites’ nutrient supply.Read moreRead less
