Protein sigma-NS

UniProtKB accession:  P03526

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Protein that binds to ssRNA and participates with protein mu-NS in forming the matrix of viral factories, which are large inclusions in the host cytoplasm where replication intermediates are assembled and viral RNA replication takes place (PubMed:11152519). Plays a role in the inhibition of the integrated stress response (ISR) to escape from host cell translational shutoff (PubMed:28794026). Participates in the disruption of stress granules (SG) through its association with host G3BP1 and mu-NS (PubMed:28794026).
