Neuraminidase Protein of Influenza A H3N2 Virus (NA)

Target
NA
Molecular classification
Enzyme, Glycoprotein, Viral protein, Neuraminidase
01

Overview

Neuraminidase (NA) is a surface glycoprotein of the influenza A H3N2 virus that plays a crucial role in viral release and spread by cleaving sialic acid residues from host cells. It is a homotetramer with a globular head containing a conserved catalytic site. NA is a major target for antiviral drugs like oseltamivir and zanamivir.
