Nrd1 and Nab3 binding to CHT2 , SLX4 and TRA1 transcripts. (A, B) Coverage of unique cDNAs from Nrd1, Nab3 and Pol II (Rpb2) PAR-CLIP data [6, 29] on Watson (+) and Crick (-) strands is shown as black histograms. ‘Selected intervals’ indicates genomic regions with a read coverage FDR ≤0.01 used for pyMotif analyses. Locations of cross-linked Nrd1-Nab3 motifs (this work), annotated XUTs, CUTs, SUTs (if present), polyadenylation sites and UTRs [22, 38–41] are included as rectangles. Genomic features located on the Watson (+) strand are indicated in red, whereas features on the Crick strand (-) are indicated in blue.
