RNA1fs accumulation requires many RdRp motifs. (A) Map of eight conserved RdRp motifs in protein A. Deletions of RdRp motifs are labeled R1 through R8. Deletions of spaces between RdRp motifs are labeled S1 through S5. Yeast cells were transformed with pF1fs alone or together with full-length or deletion mutant pFAD692E-YFP. The asterisk in panel B denotes a protein A mRNA band. Total RNAs and proteins were extracted and analyzed as described in the legend to Fig. 7 (B to F). Averages from six independent experiments are shown.
