Alternative IES excision in ICOP and other relevant KDs. (A) Schematic representation of analyzed IES excision events. (B) Distribution of genome-wide alternative IES excision (percentage per IES) for different KDs. (C) Length distribution of alternatively excised IESs for each KD. The reference length distribution for all IESs is given above (“standard IES excision”). (D) Origin of alternatively excised IESs in the “forbidden” peak. The reference length is plotted for all alternatively excised 34–44 bp IESs. (E) Length distribution of partial external and partial internal alternative excision events for the KDs.
