Co-Director, SPARC Drug Discovery Centre
Dr. Daniela Rotin completed her PhD with Dr. Ian Tannock at the Ontario Cancer Institute, Toronto, working on ion transport and metabolism in cancer, followed by two Postdoctoral Fellowships, first at The Hospital for Sick Children, Toronto, with Dr. Sergio Grinstein, working on ion transport, and second with Dr. Joseph Schlessinger in NYU Medical Center in NY, U.S., working on Signal Transduction.
She has been an Independent Investigator in the Cell Biology Program, The Hospital for Sick Children, Toronto, since 1992, where she is now a Senior Scientist, as well as a Professor of Biochemistry Department at University of Toronto. She is also the Co-Director of the SPARC-Drug Discovery Centre at The Hospital for Sick Children.
The Rotin group has been studying the ubiquitin system, particularly the Nedd4 family of E3 ubiquitin ligases. They are studying the biochemistry, structure and function of these E3 ligases, as well as their physiological functions using cells, tissue organoids and model organisms.
They have developed proteomic methodologies to globally identify substrates for E3 ubiquitin ligases, and have subsequently focused their studies on some of the membrane proteins that were identified in these and related screens (e.g. the sodium channel ENaC, the FGF receptor 1, LAPTM proteins). These studies are relevant to human diseases such as hypertension, cystic fibrosis and cancer.
