Project Details
Cell viability and function requires maintenance of the correct protein composition and distribution within the cell at all times. This proteostasis is regulated by mechanisms that control protein synthesis, localisation and degradation. Cells can also respond to external signals to alter proteostasis, allowing them to adapt to changes in their environment. In cells of the immune system, expression of many important receptors is regulated by addition of the protein ubiquitin by the MARCH family of ligases. MARCH ubiquitination thus plays major roles in immunity against pathogens and cancer. The MARCHs also play important roles in control of infection by viruses. However we know very little about MARCH specificicity and regulation.
This project will employ biochemical techniques, microscopy, proteomics, and CRISPR-Cas9 technology to characterise the function of the MARCH family; identify novel MARCH substrates; and characterise the machinery involved in ubiquitination by MARCHs. Our goal is to develop novel therapeutic approaches to fight infection and cancer based on manipulation of membrane protein ubiquitination.
