H14N5 HA (His Tag) recombinant protein
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.

A DNA sequence encoding the Influenza A virus (A/mallard/Astrakhan/263/1982(H14N5)) hemagglutinin (P26136) (Met1-Lys342), termed as HA1, was expressed with a C-terminal polyhistidine tag.
The recombinant HA1 subunit of Influenza A virus (A/Mallard/Astrakhan (Gurjev)/263/1982(H14N5)) comprises 341 amino acids and has a predicted molecular mass of 37.4 kDa. The apparent molecular mass of the protein is approximately 53.7 kDa in SDS-PAGE under reducing conditions.
