Protein quality control & ageing

The functional state of a cell is defined by its proteome, i.e. abundance, localisation, turnover and mobility of all proteins and their organisation in complexes and organelles. Numerous cellular systems contribute to proteome homeostasis through prevention, detection and removal of misfolded and damaged proteins. Proteome homeostasis declines with ageing and in some cancers and neurodegenerative disorders, resulting in the accumulation of abnormal proteins and loss of cell functionality.

Our aim is to understand how cells recognise abnormal proteins and how protein quality systems change in healthy versus diseased or aged cells. We employ a multidisciplinary approach combining molecular and cell biology techniques, biochemistry, computational biology and genomic and proteomic approaches that allow us to follow proteome dynamics down to the single cell level.
