Figure 6. Contribution of conserved elements in double-domain ENEs to RNA stabilization.
(A) TWIFB1_OSa ENE. Nucleotide shading is as in Figure 2. Mutants designated Mut1-Mut6 were used in the experiments shown in (B). (B) β-globin constructs (βΔ1,2) containing either the WT or a mutant TWIFB1_OSa ENE were transiently expressed in HEK293T cells and analyzed as described in Figure 5. The bars depict the average values from three experiments ±SD.
