Quantitation of RBP-binding sites in different classes of intron RNAs.

<p>Bar graphs showing the number of (A) FLEXI RNAs, (B) Other Ensembl GRCh38-annotated short introns (≤300 nt), and (C) Ensembl GRCh38-annotated long introns (>300 nt) that have a CLIP-seq-identified binding site for the indicated RBP in a merged dataset for the K-562, HEK-293T, HeLa S3, and UHRR cellular RNA samples. Bars graphs are color coded by RBP function as shown at the top. Asterisks above the bars in panels B and C indicate the 53 proteins identified as binding ≥30 different FLEXIs in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1011416#pgen.1011416.g004" target="_blank">Fig 4A</a>.</p> <p>(PDF)</p>
