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