Specific occupancy of target promoters by CREM and CREB. A-D. Graphic representation of ChIP-seq results as. wig format files in UCSC web browser at the indicated loci. The same format has been used for Figs. 6 and 7 as well as Additional file 1, Figs. S4 and 5. The ChIP-seq results for CREB and CREM in GC1-spg and testis haploid cells respectively are shown along with results for H3K4me3 in GC1-spg cells (K4-GC1) and testis (K4-T). In addition, the mammalian conservation track from the UCSC browser is also included. CREM and CREB binding peaks are indicated by arrows.
