Key result
Removal of a large intron region and an 85-nucleotide 3' exon region from influenza virus NS1 mRNA alleviated a block in splicing, increasing splicing efficiency to 48% compared to undetectable levels in intact mRNA.

Identifies specific intron and exon regions in influenza virus NS1 mRNA that inhibit splicing.
Nemeroff et al. (1992) studied Influenza Virus NS1 mRNA splicing (in vitro). Deletion of intron and 3' exon regions in NS1 mRNA vs. Intact wild-type NS1 mRNA was evaluated on In vitro splicing efficiency. Removal of a large intron region and an 85-nucleotide 3' exon region from influenza virus NS1 mRNA alleviated a block in splicing, increasing splicing efficiency to 48% compared to undetectable levels in intact mRNA.
