Introduction
Viruses with anti-sense RNA genomes, such as the influenza virus carry three core polypeptides inside their viral capsids in order to successfully enter a host and initiate the viral replication cycle. Especially important for viral replication and coordination with the host cell's replication machinery is a protein able to bind single-strand RNA scripts (ssRNA), forming ribonucleoprotein complexes (RNPs). This protein is commonly referred to as nucleoprotein (NP). The NP binds and transports viral RNA scripts to and from the host cell nucleus for transcription, replication, and packaging into new virions. When NP binds RNA it is structure specific but not sequence specific, meaning NP will bind only ssRNA but will bind any ss-RNA script, viral or non-viral. Beyond the transport function, NP is an essential mediator between host and virus and coordinates complex processes during viral replication. Due to its important function, NP is intensively studied as a potential drug target for antiviral pharmaceuticals. .[1]
