- Activity summary
Influenza A Virus Hemagglutinin also known as hemagglutinin or influenza HA is a surface glycoprotein found on the influenza A virus. Hemagglutinin has a mass of approximately 75 kDa and serves as an important player in the virus's ability to infect host cells. It is expressed on the exterior membrane of the influenza virus and allows the virus to attach to and enter host cells initiating the infection process. This protein comes in various subtypes adding complexity to the virus's infection strategies and complicating vaccine development.
- 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.
- Associated diseases and disorders
Hemagglutinin is deeply connected to seasonal influenza outbreaks and pandemics. Alterations in the hemagglutinin protein such as mutations and antigenic drifts or shifts can lead to new influenza strains with pandemic potential. The interaction of hemagglutinin with host immune responses and its capability to change allows the virus to evade immune detection. Neuraminidase inhibitors a class of antiviral drugs target enzymes closely related to hemagglutinin to prevent the spread of infection showcasing hemagglutinin's centrality in both infection and therapeutic intervention strategies.
