C, D. Distribution profiles of average RNAchIP signal in both IP (warm colors) and input (blue colors) over ±2kb centered on intronic (C) and exonic (D) CACACA hexameric motifs oriented in the same orientation (sense) or in opposite orientation (antisense) relative to the overlapping annotated transcript. The antisense CACACA motifs were obtained by querying the transcript sequences with the TGTGTG motif.
