Answer :
In order to effectively induce membrane fusion, the hemagglutinin-neuraminidase (HN) protein, which is in charge of virus attachment, interacts with the fusion protein in a virus type-specific manner.
What distinguishes hemagglutinin from neuraminidase?
The main distinction between hemagglutinin and neuraminidase is that while neuraminidase cleaves sialic acid from viral receptors to release the progeny viruses from the host cells, hemagglutinin binds with cell target cells' surface sialic acid promotes viral attachment to host cells.
What part does neuraminidase play in the influenza virus?
Influenza Hemagglutinin (HA) glycoprotein is typically used by a viruses to bind to cell surface sialic acid receptors, and neuraminidase (NA) glycoprotein is used to cleave the receptor and release the virus.
