USP 22是一种细胞质和细胞核去泛素化酶。Cai等人表明,细胞质USP 22在病毒感染后使输入蛋白KPNA 2去泛素化并稳定,这促进IRF 3的核转位和细胞抗病毒应答。
USP22 is a cytoplasmic and nuclear deubiquitinating enzyme. Cai et al. show that the cytoplasmic USP22 deubiquitinates and stabilizes the importin protein KPNA2 after viral infection, which promotes nuclear translocation of IRF3 and cellular antiviral responses.
