FIGURE 3

Transcriptional regulation by long ncRNA. Long ncRNAs can conduct transcriptional regulation of target genes by: (A) transcriptional interference. The purple rectangle represents the promoter region for SER3, and the blue boxes are SER3 upstream activating sequence (UAS) elements; (B) interacting with promoters. The short purple rectangle represents the minor promoter, and the long purple rectangle represents the major promoter; (C) interacting with transcriptional factors. ei and eii are two ultraconserved enhancers.
