CC -!- FUNCTION: Binds to sialic acid-containing receptors on the cell CC surface, bringing about the attachment of the virus particle to CC the cell. This attachment induces virion internalization of about CC two third of the virus particles through clathrin-dependent CC endocytosis and about one third through a clathrin- and caveolin- CC independent pathway. Plays a major role in the determination of CC host range restriction and virulence. Class I viral fusion CC protein. Responsible for penetration of the virus into the cell CC cytoplasm by mediating the fusion of the membrane of the CC endocytosed virus particle with the endosomal membrane. Low pH in CC endosomes induces an irreversible conformational change in HA2, CC releasing the fusion hydrophobic peptide. Several trimers are CC required to form a competent fusion pore. CC {ECO:0000256|RuleBase:RU003324}. CC -!- FUNCTION: Binds to sialic acid-containing receptors on the cell CC surface, bringing about the attachment of the virus particle to CC the cell.

Several trimers are CC required to form a competent fusion pore (By similarity). CC {ECO:0000256|SAAS:SAAS00204388}. CC -!- SUBUNIT: Homotrimer of disulfide-linked HA1-HA2. CC {ECO:0000256|RuleBase:RU003324, ECO:0000256|SAAS:SAAS00046877}. CC -!- SIMILARITY: Belongs to the influenza viruses hemagglutinin family. CC {ECO:0000256|RuleBase:RU003324}.
