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 | These assays confirmed that anti-pH1N1 sera produced in ferrets reacts strongly to wild-type pH1N1 virus and pH1N1 virus with a K133N HA mutation, but not to pH1N1 virus with a G158E HA mutation |
