Protein Ubiquitylation in Pancreatic Cancer by Thomas Bonacci, Julie Roignot, Philippe Soubeyran

“…Taking into account that ubiquitylation machinery is a three-step process involving hundreds of proteins, which is countered by numerous ubiquitin hydrolases, and that the function of ubiquitylation relies on the recognition of the ubiquitin signals by hundreds of proteins containing a ubiquitin binding domain (including the proteasome), the number of possible therapeutic targets is exceptionally vast and will need to be explored carefully for each disease. …”
