Structure of the essential Commander protein trafficking complex. This project aims to provide a fundamental understanding of the structure and function of Commander, a large protein complex that controls export and recycling of internalised receptors. Commander is highly conserved throughout evolution and is essential for maintaining the homeostasis of hundreds of transmembrane receptors required for cell function and survival, regulating processes as diverse as lipid metabolism and cell adhesi ....Structure of the essential Commander protein trafficking complex. This project aims to provide a fundamental understanding of the structure and function of Commander, a large protein complex that controls export and recycling of internalised receptors. Commander is highly conserved throughout evolution and is essential for maintaining the homeostasis of hundreds of transmembrane receptors required for cell function and survival, regulating processes as diverse as lipid metabolism and cell adhesion. Despite advances in the understanding of Commander function, little is known about how Commander is assembled and interacts with other essential proteins. This project will use multidisciplinary cellular and structural biology approaches to reveal the architecture of Commander at an atomic level.Read moreRead less
The functional architecture of a unique family of lipid droplet proteins. Eukaryotic cells are distinguished by the presence of membrane-bound compartments called organelles. This project will use structural biology to determine how essential proteins called sorting nexins (SNXs) regulate membrane interactions required for lipid droplet formation. These interactions are essential for life, controlling protein and lipid homeostasis needed for cell survival. The major outcome of this proposal will ....The functional architecture of a unique family of lipid droplet proteins. Eukaryotic cells are distinguished by the presence of membrane-bound compartments called organelles. This project will use structural biology to determine how essential proteins called sorting nexins (SNXs) regulate membrane interactions required for lipid droplet formation. These interactions are essential for life, controlling protein and lipid homeostasis needed for cell survival. The major outcome of this proposal will be a fundamental understanding of how SNXs control this process, and the work will significantly strengthen our international collaboration in this emerging area. The knowledge has potential future translation in the treatment of neurodegenerative disorders where dysregulation of these proteins is known to cause disease. Read moreRead less
