Hemagglutinin - Wikipedia
In molecular biology, hemagglutinins (alternatively spelt haemagglutinin, from the Greek haima, 'blood' + Latin gluten, 'glue') are receptor-binding membrane fusion glycoproteins produced by viruses in the Paramyxoviridae and Orthomyxoviridae families. [1][2] Hemagglutinins are responsible for binding to receptors on host cells to initiate viral...
Hemagglutinin (influenza) - Wikipedia
Influenza hemagglutinin (HA) or haemagglutinin [p] (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, [1] [2] having multifunctional activity as …
Influenza Hemagglutinin Structures and Antibody Recognition
Hemagglutinin (HA) is most abundant glycoprotein on the influenza virus surface. Influenza HA promotes viral entry by engaging the receptor and mediating virus–host membrane fusion. At the same time, HA is the major antigen of the influenza virus.
Hemagglutinin Structure and Activities - PubMed
Oct 1, 2021 · Hemagglutinins (HAs) are the receptor-binding and membrane fusion glycoproteins of influenza viruses. They recognize sialic acid-containing, cell-surface glycoconjugates as receptors but have limited affinity for them, and, as a consequence, virus attachment to cells requires their interaction with several virus HAs.
Hemagglutinin | Viral Structure, Receptor Binding & Antigenicity ...
hemagglutinin, any of a group of naturally occurring glycoproteins that cause red blood cells (erythrocytes) to agglutinate, or clump together. These substances are found in plants, invertebrates, and certain microorganisms.

Structural Biology of Influenza Hemagglutinin: An Amaranthine …
Sep 22, 2020 · Hemagglutinin (HA) glycoprotein is an important focus of influenza research due to its role in antigenic drift and shift, as well as its receptor binding and membrane fusion functions, which are indispensable for viral entry.
Hemagglutinin - an overview | ScienceDirect Topics
Hemagglutinins are proteins that possess a specific affinity for certain sugar molecules. Since carbohydrate units exist in most animal cell membranes, the hemagglutinins may attach to these receptor groups. This attachment will occur only if the …

The Hemagglutinin: A Determinant of Pathogenicity
Jan 1, 2014 · The hemagglutinin (HA) is a prime determinant of the pathogenicity of influenza A viruses. It initiates infection by binding to cell surface receptors and by inducing membrane fusion. The fusion capacity of HA depends on cleavage activation by host proteases, and it...
