Objective:

To summarize the roles of E3 ubiquitin ligases in SARS-CoV-2 infection and discuss their mechanisms at the virus-host interface, highlighting their significance in viral pathogenesis.

Approach:

Key Findings:

• E3 ubiquitin ligases are crucial for both antiviral defense and viral immune escape, with specific examples.
• SARS-CoV-2 employs host E3 ligases to inhibit immune responses and promote viral replication, illustrating the mechanisms involved.
• Differential expression of E3 ligases in various tissues affects COVID-19 severity and symptoms, with examples of specific ligases.

Interpretation:

The interplay between antiviral and proviral E3 ligases is critical in the pathogenesis of SARS-CoV-2, suggesting that targeting these pathways may offer new therapeutic strategies, which should be elaborated.

Limitations:

• Current research primarily focuses on binary interactions between individual E3 ligases and viral proteins, with a call for more systemic studies.
• The complexity of E3 ligase networks and their dual roles complicate therapeutic targeting, suggesting the need for innovative approaches.

Conclusion:

Understanding E3 ubiquitin ligases' roles in SARS-CoV-2 infection could lead to innovative antiviral therapies, emphasizing the importance of future research in this area.
