Nucleoprotein, encoded by influenza A virus, is an attractive target due to its high conservative and multifunctional nature during virus life cycle. In addition, NP does not have any counterpart in the cell, and hence compounds targeting NP might have less off-target side effects. NP encapsulates the negative strand viral RNA by is binding to 24 bases of RNA, protecting it from nucleases. The encapsulated genomic RNA is termed the ribonucleoprotein (RNP). The active RNP imports into the nucleus through cellular importin α/β pathways, and serves as template for transcription and replication.
