The aim of the present investigation was to discover the genetic relationships of 2009 pandemic novel influenza A/H1N1 virus (NIV) external antigens Hemagglutinin (HA) and Neuraminidase (NA) with other influenza viruses by performing phylogenetic, comparative and statistical analyses. Phylogenetic trees

Two surface glycoproteins of influenza virus, haemagglutinin (HA) and neuraminidase (NA), play opposite roles in terms of their interaction with host sialic acid receptors. HA attaches to sialic acid on host cell surface receptors to initiate virus infection while NA

Interactions that facilitate transmembrane domain (TMD) dimerization have been identified mainly using synthetic TMDs. Here, we investigated how inherent properties within natural TMDs modulate their interaction strength by exploiting the sequence variation in the nine neuraminidase subtypes (N1-N9) and the
