Influenza hemagglutinin (HA) or haemagglutinin (British English) is a homotrimeric glycoprotein found on the surface of influenza viruses and is integral to its infectivity. Hemagglutinin is a Class I Fusion Protein, having multifunctional activity as both an attachment factor and membrane fusion protein. … See more Hemagglutinin (HA) in influenza A has at least 18 different subtypes. These subtypes are named H1 through H18. H16 was discovered in 2004 on influenza A viruses isolated from black-headed gulls from See more HA is a homotrimeric integral membrane glycoprotein. It is shaped like a cylinder, and is approximately 13.5 nanometres long. HA trimer is made of three identical monomers. … See more Since hemagglutinin is the major surface protein of the influenza A virus and is essential to the entry process, it is the primary target of neutralizing antibodies. These antibodies against flu have been found to act by two different mechanisms, mirroring the dual … See more • Jmol tutorial of influenza hemagglutinin structure and activity. • PDB Molecule of the Month Hemagglutinin (April 2006) • Influenza Research Database Database of influenza protein sequences … See more HA plays two key functions in viral entry. Firstly, it allows the recognition of target vertebrate cells, accomplished through the binding to these cells' sialic acid-containing receptors. Secondly, once bound it facilitates the entry of the viral genome into the target cells … See more • Viruses portal • FI6 antibody • Phytohemagglutinin • Hemagglutinin See more WebHemagglutinin (HA) protein is an antigenic glycoprotein found on the surface of the influenza viruses, responsible for binding the virus to the cell that is being infected. The name "hemagglutinin" comes from the protein's ability to cause red blood cells (erythrocytes) to clump together ("agglutinate") in vitro. details of HA protein function. WebSweating.
