(A) Malat1 RAP-RNA[FA-DSG] enrichment at exons and introns, similar to Figure 2B.
(B) Comparison of Malat1 RAP-RNA[FA-DSG] enrichment for the exons (gray) and introns (black) of all genes or of significant gene sets. See also Figure S3.
(C) Malat1 RAP-RNA[FA-DSG] sequencing reads mapping to Hnrnpdl and (D) Tial1, two highly enriched genes encoding RNA-binding proteins. Gray rectangles highlight conserved introns containing RNA elements that control alternative splicing.
