Supplementary information

NP-I also known as NP protein or NP-BSA functions as a nucleoprotein component of ribonucleoprotein complexes. It has a mass of 56 kDa. Expression occurs in both the cytoplasm and nucleus of infected cells. Ribonucleoproteins with NP-I encapsulate viral RNA which helps in the process of viral replication and transcription. NP-I is essential for forming the ribonucleoprotein core stabilizing the viral genome and facilitating interactions with the polymerase.
Biological function summary

NP-I plays important roles in the life cycle of certain viruses. It associates with NP-TX1 another protein component to ensure effective assembly of the viral replication machinery. NP-I is also part of a complex that maintains the integrity of the viral RNA. It modulates host cell responses to viral infection by interacting with host cellular proteins impacting viral pathogenicity and replication efficiency.

Pathways

NP-I interacts with the RNA replication and transcription processes of viruses. It participates in the influenza virus life cycle pathway where NP protein coordinates with polymerase subunits like PB1 PB2 and PA to facilitate RNA synthesis. These interactions and pathways are critical for understanding how viruses exploit host cellular machinery to perpetuate their replication cycles. Specifically NP-I contributes to the assembly and regulation of viral RNA genomes within host cells.

NP-I is connected to viral infections like influenza. It has a pivotal role in facilitating viral replication and immune evasion influencing the severity of influenza manifestations. The interaction between NP-I and host proteins like interferon regulators can modulate immune responses potentially leading to immune system disorders. By understanding these interactions scientists can develop therapeutic interventions targeting NP-I to control or mitigate influenza viral infections.
