Figure 7.

Introns dependent on DDX39B expression have U-poor/C-rich py tracts. (A) Violin plots depicting the nucleotide frequencies in py tracts of introns retained more upon DDX39A (n = 34) and DDX39B (n = 89) depletion compared to introns unchanged (n = 100) upon either knockdown. Statistical significance is calculated using Kruskal–Wallis test (****P ≤ 0.0001; ns = not significant). (B) Sequence comparisons of py tracts of introns retained more upon DDX39A or DDX39B depletion and unchanged introns.
