Protein detail:


Protein name Nonstructural Protein 1
Uniprot protein ID C3W611
Protein length 219 amino acids
Protein description The non-structural protein 1 (NS1) is a crucial influenza A virus immune regulator that antagonizes antiviral response. The NS1 protein counteracts the production of IFNs and the activities of IFN-induced proteins that restrict influenza virus replication. Furthermore, NS1 is a multifunctional regulatory viral protein that plays a critical role as a posttranscriptional regulatory factor in the life cycle of influenza virus; specifically, binding virion RNA. NS1 protein consists of 2 distinct functional domains connected by a flexible linker region (LR): an N-terminal RNA- binding domain (RBD, aa 1-73) and a C-terminal effector domain (ED, aa 74-207). The nucleotide sequence (NLS) (aa 35-41) overlaps the sequences needed for dsRNA binding.
