Conformational targeting enabled the creation of a ubiquitin variant that specifically inhibits the deubiquitinating enzyme ubiquitin-specific protease 7 (also known as HAUSP). Generation of such tools is essential to unravel the complexities of ubiquitin signaling, but how general is this approach?
