HA/Hemagglutinin Protein is a type of viral fusion protein. It mediates the fusion of the membrane of endocytosed virus particles with the endosomal membrane, responsible for the penetration of the virus into the cytoplasm. HA/Hemagglutinin Protein binds to sialic acid receptors, allowing the virus particles to attach to cells. HA/Hemagglutinin Protein is a homotrimer consisting of a globular head domain located at the top of the stem domain near the membrane. Hemagglutinin/HA Protein, H11N2 (AAY85533, HEK293, His) is the recombinant Virus-derived Hemagglutinin/HA protein, expressed by HEK293 , with C-His labeled tag.
