Protein detail:


Protein name Hemagglutinin
Uniprot protein ID C3W627
Protein length 566 amino acids
Protein description The HA protein is translated as an uncleaved HA0 precursor protein, folded as a trimer, and glycosylated and acylated. The HA 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 either through clathrin-dependent endocytosis or through 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.

Evidence pCR2.1 plasmids encoding To/08 HAs possessing the D35N, T82K, Y94H, K141E, R189K, R209K, or E275K mutation were generated by using a QuikChange site-directed mutagenesis kit (Stratagene, Cedar Creek, TX).
