Ubiquitin Specific Peptidase 7 (USP7), also known as Herpes Virus-associated Ubiquitin Specific Protease (HAUSP), is a widely expressed deubiquitinating enzyme belonging to the peptidase C19 family (1). It has a predicted molecular weight of 130 kDa (2). Human USP7 is 1102 amino acids (aa) in length and shares 99% aa sequence identity with the mouse and rat orthologs (2,3). USP7 consists of a cysteine peptidase core (aa 208-560) that is flanked by an N-terminal TRAF-like domain (aa 50-205) and two C-terminal protease-resistant domains (aa 622-801 and 885-1061) (2,3). USP7 can be phosphorylated at Ser18 and Ser963 and ubiquitinated at Lys869 (2,4). USP7 was initially identified as a p53-interacting protein that deubiquitinates p53, thereby stabilizing the protein and inducing p53-dependent cell growth arrest and apoptosis (5). USP7 also targets the p53 regulatory proteins MDM2, MDMX, and Daxx, the epigenetic regulator Histone 2B, and the transcription factor FoxO4 (4,6-10). Additionally, USP7 interacts with the HSV-1 immediate early protein ICP0, contributing to the stabilization and transactivation capability of ICP0 during HSV-1 infection (1,11,12).
