Function

Mediates the nuclear export of encapsidated genomic RNAs (ribonucleoproteins, RNPs). Acts as an adapter between viral RNPs complexes and the nuclear export machinery of the cell. Possesses no intrinsic RNA-binding activity, but includes a C-terminal M1-binding domain.

Biological Context

Subcellular Location: Virion; Host nucleus

Product Specifications

Recombinant Influenza B virus Nuclear export protein (NS) is a recombinant protein from Influenza B virus (strain B/Yamagata/1/1973), expressed in E.coli, covering amino acids 1-122aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 21.8kDa, purity Greater than 85% as determined by SDS-PAGE..

Protein Biology

Function

Mediates the nuclear export of encapsidated genomic RNAs (ribonucleoproteins, RNPs). Acts as an adapter between viral RNPs complexes and the nuclear export machinery of the cell. Possesses no intrinsic RNA-binding activity, but includes a C-terminal M1-binding domain. This domain is believed to allow recognition of RNPs bound to the protein M1. Since protein M1 is not available in large quantities before late stages of infection, such an indirect recognition mechanism probably ensures that genomic RNPs are not exported from the host nucleus until sufficient quantities of viral mRNA and progeny genomic RNA have been synthesized. Furthermore, the RNPs enter the host cytoplasm only when associated with the M1 protein that is necessary to guide them to the plasma membrane. May down-regulate viral RNA synthesis when overproduced

Subcellular Location

Virion; Host nucleus

Subunit

Interacts with protein M1. May interact with host nucleoporin RAB/HRB and exportin XPO1/CRM1

Gene: NS  |  Organism: Influenza B virus (strain B/Yamagata/1/1973)  |  Synonyms: Non-structural protein 2
