Fig. 6From: Stable intronic sequence RNAs (sisRNAs) are selected regions in introns with distinct propertiesSpecific TFBSs are enriched in sisRNAs. The enrichment of TFBS motifs was plotted for (a) the introns without any sisRNAs versus the sisRNAs identified by RefSeq genes, and (b) the RefSeq sisRNAs versus the Ensembl sisRNAs. c UCSC genome browser screenshot of Stat3 shows it is highly expressed in the cytoplasmBack to article page
