A global pandemic COVID-19 resulting from SARS-CoV-2 has affected a significant portion of the human population. Antiviral innate immunity is critical for controlling and eliminating the viral infection. Ubiquitination is extensively involved in antiviral signaling, and recent studies suggest that ubiquitin-like proteins (Ubls) modifications also participate in innate antiviral pathways such as RLR and cGAS-STING pathways. Notably, virus infection harnesses ubiquitination and Ubls modifications to facilitate viral replication and counteract innate antiviral immunity. These observations indicate that ubiquitination and Ubls modifications are critical checkpoints for the tug-of-war between virus and host. This review discusses the current progress regarding the modulation of the SARS-CoV-2 life cycle and antiviral innate immune pathways by ubiquitination and Ubls modifications. This paper emphasizes the arising concept that ubiquitination and Ubls modifications are powerful modulators of virus and host interaction and potential drug targets for treating the infection of SARS-CoV-2.
