Function

Forms the head of the spikes and mediates the recognition of specific host cell surface glycans. It is the viral hemagglutinin and an important target of neutralizing antibodies. In sialic acid-dependent strains, VP8* binds to host cell sialic acid, most probably a ganglioside, providing the initial contact.

Biological Context

Subcellular Location: Virion

Homotrimer. The trimer is coiled-coil stabilized by its C-terminus, however, its N-terminus, known as antigen domain or 'body', seems to be flexible allowing it to self-associate either as a dimer or a trimer
