Influenza A virus neuraminidase protein (N9) (N9)

Target
N9
Molecular classification
Enzyme, Viral protein, Glycoprotein
01

Overview

The neuraminidase (NA) protein of Influenza A virus, specifically the N9 subtype, is a surface glycoprotein critical for viral replication and spread. It functions as an enzyme that cleaves terminal sialic acid residues from host cell glycans, facilitating the release of newly formed virions from infected cells and preventing viral aggregation. NA is a validated antiviral drug target, with inhibitors like oseltamivir and zanamivir blocking its enzymatic activity.
