U2AF1 plays a critical role in global co-transcriptional splicing (Fraction chrRNA-seq)
In order to measure the impact of U2AF1 on co-transcriptional splicing, we treated HeLa cells with control siRNA or U2AF1 siRNA. To measure co-transcriptional splicing, we fractionated HeLa cells into cytosolic (Cyt), nucleoplasm (NP), and chromatin/particle (Chr) fractions. We purified total RNA from Chr compartment, spiked in with in vitro transcribed EGFP and FireFly luciferase RNA for data normalization, depleted ribosomal RNAs, and constructed two independent libraries for RNA-seq. Overall design: Characterization of co-transcriptional splcing  after U2AF1 knock-down in Hela cells
