The HA1 Subunit of Haemagglutinin Protein (HA) from the Influenza A – G4 (EA) H1N1 virus plays a major role in the infection of a cell and is therefore a very important target for the development of antibody tests or for vaccine development. The HA1 domain binds to the cell surface receptor and thus brings virus particle into it. The HA1 protein belongs to the Class I viral fusion proteins and plays an important role in the determination of host range restriction and virulence. The protein is responsible for the penetration of the virus into the cell cytoplasm by mediating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane.
