Figure 2From: Inability of NS1 protein from an H5N1 influenza virus to activate PI3K/Akt signaling pathway correlates to the enhanced virus replication upon PI3K inhibitionSequence alignments of different NS1 proteins. Amino acid sequence alignments of NS1 proteins from different influenza A virus strains. Numbers correspond to residues in full-length proteins; shadowed boxes denote the key residues (Y89, M93, L141, E142, P162, P164, and P167) responsible for the binding of NS1 to p85β.Back to article page
