Outline of Final Research Achievements |
Avian influenza H5N1 has shown high mortality rate in human with 60%. Non-structural protein 1 (NS1) is a virulence factor of H5N1. Mutation at the 42nd residue within the RNA-binding domain (RBD) of NS1 dramatically changes the degree of pathogenicity of H5N1 in mice. We here studied the impact of this mutation on the function of RBD, and found that RBD with S42 binds double-stranded RNA (dsRNA), whereas that with P42 does not. Analysis of structural models of the RBD proteins with S42 and P42 suggested remarkable difference in the structure of the dsRNA-binding interface, whereas structural analysis did not indicate difference between those RBD proteins. Our results suggest that the single amino acid replacement induces a minor, but global structural change leading to the loss of function of NS1 thereby the change in the degree of pathogenicity In addition, PL site of NS1 may associate with down-regulation of tight junction molecules on epithelial cells in lung.
