The nucleoprotein (NP) of influenza virus covers the viral RNA entirely and it is this NP-RNA complex that is the template for transcription and replication by the viral polymerase. Purified NP forms a dynamic equilibrium between monomers and small oligomers, but only the monomers can oligomerize onto RNA. Therefore, drugs that stabilize the monomers or that induce abnormal oligomerization may have an antiviral effect, as would drugs that interfere with RNA binding. Crystal structures have been produced for monomeric and dimeric mutants, and for trimers and tetramers; high-resolution electron microscopy structures have also been calculated for the viral NP-RNA complex. We explain how these structures and the dynamic oligomerization equilibrium of NP can be and have been used for anti-influenza drug development.
