  • Relevance
    The nucleoprotein (NP) of Influenza virus encapsulates the negative strand of the viral RNA and is essential for replicative transcription. It may also be involved in other essential functions throughout the virus life cycle. As well as binding ssRNA, NP is able to self associate to form large oligomeric complexes. NP is able to interact with a variety of other macromolecules of both viral and cellular origins. It binds the PB1 and PB2 subunits of the polymerase and the matrix protein M1. "NP has also been shown to interact with at least four cellular polypeptide families: nuclear import receptors of the importin class, filamentous (F) actin, the nuclear export receptor CRM1 and a DEAD box helicase BAT1/UAP56" (Portela et al 2002).

ab66191 has been produced using purified Influenza A virus - the immunogen was not a recombinant protein.

Unfortunately we are not aware of any publications for ab66191. However, ab66191 gave a single band against purified Influenza A antigens (H1N1 and H3N2 strains) on the blot (SDS-PAGE, reducing conditions, 1ug antigen/lane). The antibody was tested...
