Protein detail:

| Uniprot protein ID | P04543 |
| Protein length | 124 amino acids |
| Protein description | Non-structural Protein 2(NS2) plays a major role in antagonizing the type I IFN-mediated antiviral response. NS2 acts cooperatively with NS1 to repress activation and nuclear translocation of host IFN-regulatory factor IRF3. NS2 Interacts with the host cytoplasmic sensor of viral nucleic acids DDX58/RIG-I and prevents the interaction with its downstream partner MAVS. Together with NS2, participates in the proteasomal degradation of host STAT2, IRF3, IRF7, TBK1 and DDX58 through a NS-degradasome involving CUL2 and Elongin-C. The degradasome requires an intact mitochondrial MAVS. Induces host SOCS1 expression. Induces activation of NF-kappa-B. Suppresses premature apoptosis by an NF-kappa-B-dependent, interferon-independent mechanism promoting continued viral replication. |
