I have been privileged to research intracellular proteolysis and particularly the ubiquitin/proteasome system for 30 years. Regulated intracellular proteolysis has undergone a meteoric rise in importance to be seen as a new layer on the cake of cellular physiology. I am particularly interested in intracellular proteolysis in relation to neurodegenerative illnesses. I spend my time in the laboratory nationally and internationally furthering this field. I reviewed the state of play in the field in a review in 2000. The meteoric rise of regulated intracellular proteolysis. Nature Reviews in Molecular Cell Biology, 1, 145-148, 2000.
Current research interests
a) I have a group of two Postdoctoral Assistants, one Senior Experimental Officer, and 3 Research Students using transgenesis to delete key genes of the ubiquitin proteasome pathway conditionally in the brain of mice to recapitulate neuropathological features of Alzheimer’s disease, Parkinson’s disease, and Amyotophic lateral sclerosis.
b) In collaboration with Professor Jun Fujita, University of Kyoto, I am pursuing the functions of a novel proteasomal subunit called gankyrin which is overexpressed in hepatocellular carcinoma. Gankyrin is also found in other complexes in the cell which regulate the phosporylation and ubiquitylation of tumour suppressors.
