Function

Q5EP31_9INFA Binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell. This attachment induces virion internalization of about two third of the virus particles through clathrin-dependent endocytosis and about one third through a clathrin- and caveolin-independent pathway. 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 induces an irreversible conformational change in HA2, releasing the fusion hydrophobic peptide. Several trimers are required to form a competent fusion pore (By similarity).[RuleBase:RU003324][SAAS:SAAS008980_004_327643]

Publication Abstract from PubMed

Two ferret-adapted H5N1 viruses capable of respiratory droplet transmission have been reported with mutations in the hemagglutinin receptor-binding site and stalk domains. Glycan microarray analysis reveals that both viruses exhibit a strong shift towards binding to 'human-type' alpha2-6 sialosides, but with notable differences in fine specificity. Crystal structure analysis further shows that the stalk mutation causes no obvious perturbation of the receptor-binding pocket, consistent with its impact on hemagglutinin stability without effecting receptor specificity.
