    The EJC is required for inclusion of exon blocks at the single transcript level. ( A ) Genome browser shot of individual long reads of mRNAs mapped to the DDX56 gene, showing control ( left ) and EIF4A3 depletion ( right ). Reference (ref.) gene is at the top , with coordinated block exons in orange. Reads are proportionally downsampled to 50 reads (total number of reads is indicated below the reads), with reads where exon blocks are skipped in orange and all other reads in green. The percentage of block-skipping reads is indicated at the right of reads. ( B ) Like A but for the FUS gene. ( C ) Schematic of block-skipping junctions, with the coordinated exon block in yellow (internal introns in orange) and surrounding exons in light blue. ( D ) Violin box plot illustrating the distribution of reads per million (RPM) spanning block-skipping junctions in control and EIF4A3 depletion conditions in mRNA long-read sequencing data sets (mean of three biological replicates). Values >60 were capped to avoid extreme outliers distorting the visualization.
