The total amount of mRNAs that bound to DDX5 was reduced after infection with VSV; however, nearly all mRNAs bound to DDX5 at a conserved GCUGCAG element, which is different from that of previously reported RNAs bound to DEAD box helicases [14,59,60], which indicated that the GCUGCAG element is a unique binding site between DDX5 and various RNAs. This evidence concerns the gene DDX5 and infection.
