Activity summary

Influenza A H7N9 Neuraminidase also known as NA or sialidase is an enzyme important in the viral replication process of the influenza virus. This protein with a molecular mass of approximately 47 kDa is expressed on the surface of the influenza A virus particles. Neuraminidase facilitates the removal of sialic acid residues from glycoproteins and glycolipids which is essential for the release of new viral particles from infected host cells. The enzymatic action is an important factor in the virus's spread within the respiratory tract of the host organism.

Biological function summary

The action of Influenza A H7N9 Neuraminidase assists in the completion of the viral life cycle. Neuraminidase in conjunction with hemagglutinin is part of a complex that allows the virus to attach and penetrate host cells efficiently. By cleaving sialic acid residues neuraminidase enables the newly formed viral particles to detach and spread facilitating infection progression. This protein's ability to disrupt cellular interactions highlights its role in viral pathogenicity an essential feature for the influenza virus's survival in host organisms.

Pathways

Neuraminidase plays a significant part in the influenza viral entry and propagation pathways. Its interaction with hemagglutinin is important for the entry of the virus into host cells. Neuraminidase's activity supports the recycling of viral particles therefore contributing to the greater viral lifecycle network. Additionally its function links with pathways of immune evasion where it helps in avoiding the host's immune response primarily through altering host cell surface molecules and aiding in the spread of infection.

Associated diseases and disorders

Neuraminidase is closely associated with the pathogenesis of influenza particularly with influenza A and its subtypes such as H7N9. Neuraminidase inhibitors like oseltamivir target this protein to prevent the spread of influenza virus and mitigate symptoms. Resistance to such inhibitors can arise making the study of neuraminidase important for developing effective treatments. Neuraminidase's activity affects both the viral lifecycle and the host's immune response underlining its role in the interactions between influenza virus proteins and host immune components.
