Function

Encapsidates the negative strand viral RNA, protecting it from nucleases. The encapsidated genomic RNA is termed the ribonucleoprotein (RNP) and serves as template for transcription and replication. The RNP needs to be localized in the host nucleus to start an infectious cycle, but is too large to diffuse through the nuclear pore complex. NP comprises at least 2 nuclear localization signals that are responsible for the active RNP import into the nucleus through cellular importin alpha/beta pathway. Later in the infection, nclear export of RNPs are mediated through viral proteins NEP interacting with M1 which binds nucleoproteins. It is possible that nucleoprotein binds directly host exportin-1/XPO1 and plays an active role in RNPs nuclear export. M1 interaction with RNP seems to hide nucleoprotein's nuclear localization signals. Soon after a virion infects a new cell, M1 dissociates from the RNP under acidification of the virion driven by M2 protein. Dissociation of M1 from RNP unmasks nucleoprotein's nuclear localization signals, targeting the RNP to the nucleus.

Activity summary

The Influenza B Virus Nucleoprotein often known as NP or flu B NP is an essential structural protein with a molecular weight of approximately 56 kDa. It plays a role in the influenza B virus lifecycle by encapsidating the viral RNA forming the ribonucleoprotein complex important for viral replication and transcription. This protein expresses in the host cell's cytoplasm and nucleus facilitating the export of vRNPs from the nucleus.

Biological function summary

The ribonucleoprotein complex formation involves nucleoproteins assembling with the viral RNA and polymerase subunits securing the genome for replication and transcription. NP interacts with both the polymerase basic 2 (PB2) and polymerase acidic (PA) proteins forming a vital part of the complex. This interaction allows the viral RNA to maintain its structure and function effectively during the virus infection cycle aiding both Influenza A and B viruses.

Pathways

NP participates in the viral replication pathway supporting the influenza virus propagation in infected cells. It associates closely with viral RNA polymerases and is integral to the transcription and replication of the viral RNA genome. Other key proteins involved in these pathways include the polymerase basic 1 (PB1) protein essential for synthesizing viral mRNA and the matrix protein (M1) which aids in vRNA encapsidation and budding.

Associated diseases and disorders

NP relates closely to influenza B infections contributing to the clinical symptoms of flu B such as fever and respiratory issues. This protein is also a potential target for vaccine and therapeutic development against influenza B. NP shares a connection with the M2 protein another target in antiviral strategies given its role in proton channel activity and viral uncoating. Understanding NP's role can guide the creation of flu B antibodies and influenza A and B antibodies to reduce disease severity or prevent flu infections.
