• "Are you claiming that ubiquitination is specific for lysine residues, or are you predicting that as a hypothesis that you are interested in testing?"
• "We continued and demonstrated that, unlike the paradigm in the field until that time, that degradation of proteins in the lysosome proceeds independently from the ubiquitin system - the two proteolytic pathways are actually linked to one another, and ubiquitination is required for stress-induced lysosomal degradation of cellular proteins."
• "Interestingly, the ligase involved in BSA ubiquitination is E3a that was discovered during my graduate studies."
