General annotation (Comments)

Function	Binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell. Plays a major role in the determination of host range restriction and virulence. Class I viral fusion protein. Responsible for penetration of the virus into the cell cytoplasm by mediating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane. Low pH in endosomes induce an irreversible conformational change in HA2, releasing the fusion hydrophobic peptide. Several trimers are required to form a competent fusion pore. Spearmint SPM013829 Binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell. Plays a major role in the determination of host range restriction and virulence. Class I viral fusion protein. Responsible for penetration of the virus into the cell cytoplasm by mediating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane. Low pH in endosomes induce an irreversible conformational change in HA2, releasing the fusion hydrophobic peptide. Several trimers are required to form a competent fusion pore By similarity. RuleBase RU003324V0
Subunit structure	Homotrimer of disulfide-linked HA1-HA2. Spearmint SPM013829 Homotrimer of disulfide-linked HA1-HA2 By similarity. RuleBase RU003324V0
Subcellular location	Virion membrane. Spearmint SPM013829
Sequence similarities	Belongs to the influenza viruses hemagglutinin family. RuleBase RU003324V0
