Summary of scientific research
Dr Ciechanover's current research focuses on the regulation of transcriptional factors, tumour suppressors, and onco-proteins, and the development of novel modalities for the treatment of diseases such as malignancies and neurodegenerative disorders based on a known mechanism of action and aberrations in the activity of the ubiquitin system which he co-discovered.
