Ubiquitin specific peptidase 7 (USP7) is a deubiquitinating enzyme (DUB) that removes ubiquitin tags from specific protein substrates in order to alter their degradation rate and sub-cellular localization. USP7 has been proposed as a therapeutic target in several cancers because

Deubiquitinating enzymes (DUBs) catalyze the removal of ubiquitin, thereby reversing the activity of E3 ubiquitin ligases and are central to the control of protein abundance and function. Despite the growing interest in DUBs as therapeutic targets, cellular functions for DUBs
