  1. ...is consistent with cell type–specific activity commonly seen in enhancers (Fig. 3A). Out of 1506 motif-focused sequences tested, 1004 were classified as active in HepG2, whereas only 52 were classified as active in K562. For genomic LTR18A, 786 (123 from hg19) were active in HepG2 and 31 (four from hg19) were...
  2. ...of a single TP53 canonical motif. By combining machine learning with a meta-analysis of TP53 ChIP-seq data sets, we identified a core set of more than 1000 responsive enhancers in the human . This TP53 cistrome is invariably used between cell types and experimental conditions, whereas differences among...
  3. ...with a luciferase coding sequence in place of GFP. (D) Comparison of MPRA-based and luciferase-based enhancer activity measurements, with each shape representing a specific test sequence. Test sequences are artificial, with repeats of RFX (square), AP1 (circle), MYBL2 (triangle), and NFYshort (diamond) motifs...
  4. ...near Activator Protein 1 (AP-1) binding sites that reside in DNase I Hypersensitive Sites (DHS) and regions annotated as Enhancers. In these regions, we found that sequence features directly adjacent to the core motif distinguish high from low activity AP-1 sites. Some nearby features are motifs...
  5. .... For example, the ENCODE Project Consortium and other efforts have identified thousands of candidate enhancers in mammalian s on the basis of such marks or their correlates (e.g., EP300 ChIP-seq, H3K27ac ChIP-seq, and DNase I hypersensitivity) in diverse cell lines and tissues (Visel et al. 2009; The ENCODE...
  6. ..., hinging on the precise binding of transcription factors (TFs) and cofactors to gene regulatory elements such as promoters and enhancers. Although it is relatively routine to profile -wide DNA binding landscapes of proteins, identifying the specific proteins that bind to, and regulate the transcription of...

  7. .... Indeed, enrichment of CTCF and Su(Hw) in module 11 suggests this module harbors insulators. Similarly, dinucleotide repeats of GA (bound by GAGA binding factor Trl) and CA are known to be features of fly enhancers (Yanez-Cuna et al. 2014). One of the promoter modules is comprised of tRNAs, and cis...
  8. ...-specific ones (Fig. 5C).View larger version: In this window In a new window Figure 5. Cell-type–specific enhancers correlate with cell-type–specific TAD borders. (A) Venn diagram representing the number of enhancers in neuronal and embryonic Drosophila cells as identified by STARR-seq. Enhancers were...
  9. ...in mouse photoreceptors. First, we identified sequence features that predict CRX occupancy in vivo (as determined by ChIP-seq), and we compared these to sequence features that are correlated with enhancer activity (as measured by MPRA). In addition, we assayed the effect of inactivating mutations...
  10. ...to the enhancers. Dinucleotide repeats that we detected on all TFBSs (Supplemental Fig. S2) and that had been previously characterized as general enhancer features (Yanez-Cuna et al. 2014) contribute to the periodic nucleosome positioning signal underlying HNAR center (Kaplan et al. 2009) and, at the same time...
