OTUD1 (OTU Deubiquitinase 1): OTUD1 (OTU Deubiquitinase 1) is an enzyme that removes ubiquitin from ubiquitinated proteins, playing a crucial role in regulating their degradation, signalling, and various cellular processes. OTUD1 contributes to the control of immune responses and cell signalling pathways by modulating the stability of specific protein targets. Its role in maintaining protein homeostasis and regulating immune signalling highlights its potential significance in immune-related diseases and cancer.
