Identification of novel CREB occupied regulatory elements and transcripts. A. Pie chart indicating the frequency of occurrence of consensus or mutated CRE and half CREs at the CREM and CREB intergenic binding sites. B-C. Graphic representation of ChIP-seq results in UCSC web browser at the indicated loci using the nomenclature described in Fig. 4, with the addition of the GC1-spg pol II ChIP-seq data set. In panels B-C, the presence and direction of transcription of potential novel transcripts in the regions covered by elongating pol II are indicated by arrows.
