Comparison of predicted and identified binding sites. (A) Overview of the percentage (y-axis) of genes in genomic features (x-axis) that contain Nrd1 (blue) or Nab3 (red) motifs in their sequence. (B) The percentage of genomic features that contained cross-linked Nrd1 or Nab3 motifs. (C) The percentage of all Nrd1 and Nab3 motifs in gene/feature sequences found in the PAR-CLIP data analyses. (D) The distribution of cross-linked motifs over UTR and exon sequences. ncRNA, non-coding RNA; snRNA, small nuclear RNA.
