Influenza A Virus Neuraminidase Protein N1 Subtype (NA N1)

Target
NA N1
Molecular classification
Enzyme, Viral Protein, Glycoprotein
01

Overview

The neuraminidase (NA) protein is a surface glycoprotein of influenza A viruses, specifically the N1 subtype in this case. NA is crucial for viral release by cleaving sialic acid residues, facilitating spread to new host cells. Its globular head domain contains antigenic sites susceptible to antigenic drift. It is a target for antiviral drugs like oseltamivir and zanamivir, although resistance can emerge.
