Biological function summary

Hemagglutinin facilitates the binding of the virus to sialic acid receptors on the surface of host epithelial cells. This binding triggers endocytosis allowing the virus entry into the host cell. Hemagglutinin is part of a complex that works closely with neuraminidase another glycoprotein on the virus surface. The hemagglutinin-neuraminidase complex is essential for the viral life cycle balancing attachment to host cells with the release of new viral particles.

Pathways

Hemagglutinin plays a significant role in the viral infection pathway of the influenza virus. It is critical in the initial steps of the pathway that involve viral entry and fusion with the host cell membrane. Hemagglutinin's interaction with the sialic acid receptors is closely linked with the activity of neuraminidase which aids in the release stage of the infection. This interplay between hemagglutinin and neuraminidase highlights their participation in the viral replication cycle demonstrating their complementary roles.
