a, Percentages of exonic and intronic reads in CY, NP, NM polyA+ and NM polyA−RNA-seq data. b,c, UCSC genome browser view of NM polyA+ and polyA− RNA signals in the region from TSS (transcription start site) to 10 kb downstream TES (transcription end site) for FUBP1 (b) and hnRNPA2B1 (c). d, Meta profiles of NM polyA+ and polyA− RNA signals in the ±250 nt region flanking the pPAS (left) and dPAS (right). The mean read densities were normalized and shown in arbitrary units (a.u.).
