CC   -!- FUNCTION: Hemagglutinin is responsible for attaching the virus to
CC       cell receptors and for initiating infection.
CC   -!- SUBUNIT: Homotrimer. Each of the monomers is formed by two chains
CC       (HA1 and HA2) linked by a disulfide bond.
CC   -!- SIMILARITY: Belongs to the influenza viruses hemagglutinin family.
