Abstract:Ubiquitin is a small (8.6 kDa) protein that is found ‘ubiquitously’ in eukaryotic organisms and functions as a regulator of numerous cellular processes. It is a multifaceted post-translational modifier of other proteins involved in almost all eukaryotic biology. Once bound to a substrate, ubiquitin initiates a plethora of distinct signals with unique cellular outcomes known as the ‘ubiquitin code’. More recently, much progress has been made in characterising the roles of distinct ubiquitin modifications though… Show more
