Key result
Deletion of a large intron region and an 85-nucleotide 3' exon region in influenza virus NS1 mRNA allowed efficient in vitro splicing (48%) by preventing the formation of aberrantly sedimenting presplicing complexes.

Identifies specific intron and exon regions in influenza virus NS1 mRNA that inhibit splicing.
Nemeroff et al. (1992) studied Influenza virus infection (in vitro model). Deletion of specific intron and 3' exon regions in NS1 mRNA vs. Wild-type intact NS1 mRNA was evaluated on In vitro splicing efficiency. Deletion of a large intron region and an 85-nucleotide 3' exon region in influenza virus NS1 mRNA allowed efficient in vitro splicing (48%) by preventing the formation of aberrantly sedimenting presplicing complexes.
