| dc.description.abstract | Conserved tryptophan-187 facilitates homodimerization of the influenza A virus NS1 protein effector domain. We generated a mutant influenza virus strain expressing NS1-W187R to destabilize this self-interaction. NS1-W187R protein exhibited lower double-stranded RNA (dsRNA)-binding activity, showed a temporal redistribution during infection, and was minimally compromised for interferon antagonism. The mutant virus replicated similarly to the wild type in vitro, but it was slightly attenuated for replication in mice, causing notably reduced morbidity and mortality. These data suggest biological relevance for the W187-mediated homotypic interaction of NS1. | en |
