Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to ....Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to provide novel functions, thereby facilitating the evolution of specific characteristics within species.Read moreRead less
Functional genomics of light stress resistance in the model organism Chlamydomonas: combining molecular genetics, transcriptome and proteome analysis. This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii.

This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii. Comprehensive profiles of transcriptome-proteome linkage will be constructed without the complications of multicellularity for this unicellular photosynthetic model organism. We will establish a public proteome reference database and provide new microarrays and molecular markers beneficial for research in Chlamydomonas. We expect to advance understanding of high light resistance mechanisms so that it will eventually be applicable to improve productivity in crop plants growing under various environmental stress conditions.Read moreRead less
Protein degradation in mammals. One mechanism by which the regulation of protein turnover occurs is the balance between the activity of enzymes responsible for the ubiquitination and deubiquitination of target proteins. The majority of targets of this second family of enzymes are unknown. This project proposes a method for the identification of the targets of two specific mammalian deubiquitinating enzymes in order to understand their function and to begin to explore this new research field. ....Protein degradation in mammals.

This project proposes a method for the identification of the targets of two specific mammalian deubiquitinating enzymes in order to understand their function and to begin to explore this new research field. Knowledge about this new aspect of protein degradation could provide a powerful tool to test the effect of the stabilisation or removal of specific proteins in the cell and also to develop new technologies in protein production.Read moreRead less
Role of mRNA polyadenylation control in gene expression. Several benefits would come from a more complete understanding of the function of the messenger RNA poly(A) tail. It is frequently targeted by mechanisms that control cellular protein synthesis. This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce ....Role of mRNA polyadenylation control in gene expression. Several benefits would come from a more complete understanding of the function of the messenger RNA poly(A) tail. It is frequently targeted by mechanisms that control cellular protein synthesis. This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce knowledge of broad relevance to modern life sciences and its applications in medicine and biotechnology. Finally, a better understanding of yeast cellular biology is of benefit to the food and biotechnology sector of industry.Read moreRead less
Adaptive Evolution of BRCA1 in Ancestral Mammals. This project investigates adaptive evolution of BRCA1 in the early radiation of mammals. We will test the hypothesis that the evolution of mammary glands and X chromosome inactivation has resulted in modification of the BRCA1 protein sequence as it aquired new roles in these processes. We will also investigate the importance of these changes inducing compensatory changes in other parts of the protein.

Summary
800 MHz NMR spectrometer for biomolecular structure-function analysis. An understanding of how organisms function at the molecular level is central to developing the ability to fight many diseases in a rational way. This equipment will provide the capability for many different laboratories around NSW and the ACT to advance our knowledge at this fundamental level, primarily by examining the structures and functions of biomolecules such as proteins.
Novel photoprotective mechanisms and functional biodiversity of high light tolerance in the model alga Chlamydomonas. Most plants have limited capacity to avoid high light (HL) stress which commonly accompanies drought and high temperature stress. We will identify novel genes and proteins that underlie diverse mechanisms of photoprotection in unique very high light resistant (VHLR) mutants in the alga Chlamydomonas and develop new tools to screen other plants for these attributes. Depending on p ....Novel photoprotective mechanisms and functional biodiversity of high light tolerance in the model alga Chlamydomonas. Most plants have limited capacity to avoid high light (HL) stress which commonly accompanies drought and high temperature stress. We will identify novel genes and proteins that underlie diverse mechanisms of photoprotection in unique very high light resistant (VHLR) mutants in the alga Chlamydomonas and develop new tools to screen other plants for these attributes. Depending on progress, we expect to express them in the higher plant Arabidopsis as a first step towards utilization of VHLR genes for crop improvement. Understanding the mechanisms conferring HL photoprotection is a research priority in plant sciences and will further strengthen Australia's innovative contributions to the internationally networked Chlamydomonas Genome Project.Read moreRead less
The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance. The cytochrome P450 (Cyp) gene super-family is represented by over 90 sequences in the genome of the vinegar fly, Drosophila melanogaster.

To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its phenotype. By studying the effects of Cyp genes on fly survival, Cyp gene expression and regulation, and expressing selected Cyp genes in a yeast expression system, we will enhance our understanding of Cyp gene function and evolution.Read moreRead less
