Abstract
Influenza A virus is a segmented single-stranded (-)RNA virus that causes substantial annual morbidity and mortality. The transcriptome of influenza A is predicted to have extensive RNA secondary structure. The smallest genome segment, segment 8, encodes two proteins, NS1 and NEP, via alternative splicing. A conserved RNA domain in the intron of segment 8 may be important for regulating production of NS1. Two different multi-branch loop structures have been proposed for this region. A combination of in vitro chemical mapping and isoenergetic microarray techniques demonstrate that the consensus sequence for this region folds into a hairpin conformation. These results provide an alternative folding for this region and a foundation for designing experiments to probe its functional role in the influenza life cycle.
