pubmed:abstractText |
Short synthetic influenza virus-like RNAs derived from influenza virus promoter sequences were examined for their ability to stimulate the endonuclease activity of recombinant influenza virus polymerase complexes in vitro, an activity that is required for the cap-snatching activity of primers from host pre-mRNA. An extensive set of point mutants of the 5' arm of the influenza A virus viral RNA (vRNA) was constructed to determine the cis-acting elements which influenced endonuclease activity. Activity was found to be dependent on three features of the conserved vRNA termini: (i) the presence of the 5' hairpin loop structure, (ii) the identity of residues at positions 5 and 10 bases from the 5' terminus, and (iii) the presence of base pair interactions between the 5' and 3' segment ends. Further experiments discounted a role for the vRNA U track in endonuclease activation. This study represents the first mutagenic analysis of the influenza virus promoter with regard to endonuclease activity.
