A novel link between metabolism and host defence. This project aims to delineate how a protein modification that consists of the addition of a small sugar to cellular proteins, known as O-GlcNAcylation, provides a link between metabolism and complex cell functions. The model for these studies is a cell type of the immune system known as dendritic cells. Upon encountering pathogens these cells undergo metabolic changes that increase the rate of O-GlcNAcylation of proteins involved in immune respo ....A novel link between metabolism and host defence. This project aims to delineate how a protein modification that consists of the addition of a small sugar to cellular proteins, known as O-GlcNAcylation, provides a link between metabolism and complex cell functions. The model for these studies is a cell type of the immune system known as dendritic cells. Upon encountering pathogens these cells undergo metabolic changes that increase the rate of O-GlcNAcylation of proteins involved in immune responses, altering their function. This project will study how O-GlcNAcylation works and is regulated. The project expects to develop new technology and provide high-level training, increasing the competitiveness of the strategic biotechnology sector in AustraliaRead moreRead less
Biosynthesis, folding and modification of conotoxins. Disulfide-rich peptides represent a diverse family of bioactive molecules which have been developed as drugs for the treatment of severe pain. This project seeks to understand their biosynthesis and how their functional diversity is generated. Such information will assist the translation of more of these novel peptides into new drugs.
