The ubiquitination process utilizes a cascade of enzymes involving ubiquitin-activating enzymes (E1), ubiquitin-conjugating enzymes (E2), and ubiquitin-ligases (E3), to covalently attach ubiquitin with pervasive assembly possibilities, known as the ubiquitin code. As part of physiological homeostasis, ubiquitin is reversibly cleaved from proteins <em>via</em> deubiquitylating enzymes (DUBs) in a well-orchestrated process, altering the protein's fate. Among the DUBs, ubiquitin-specific protease 7 (USP7) is considered a pivotal member due to its role in regulating the stability of multiple proteins involved in various biological activities, including p53 stability, DNA damage response, transcription, epigenetics, immune response, and viral infection.
