Function

[Q6PP25_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.[RuleBase:RU003324] Binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell.

Publication Abstract from PubMed

Antimicrobial activity and solution structures of four 13-amino acid peptides derived from the fusion domain of viral hemagglutinin proteins are presented. The results show that carboxyl-terminal amidation is a key factor to switch a viral fusion domain-derived sequence into an antimicrobial peptide. Optimization of amphiphilic balance on the amidated analogue largely improves efficacy and enlarges antimicrobial spectra of these peptides. Our work indicates that viral fusion domains have potential to be engineered into potent antimicrobial peptides.
