Examples of RARa binding sites conserved among vertebrates. (A,B) Genome browser views around HoxB-Skap1 locus in mouse (A) and zebrafish (B) showing the RAR binding sites detected by ChIP-seq (in gold) in both species. All RAR sites are located in CNEs but only the RAR sites located in skap1 gene 4th intron (green box) display sequence conservation from zebrafish to human. Other RAR sites located at similar places in the murine and zebrafish loci (red boxes) are probable orthologous RAR sites but their sequences cannot be aligned between zebrafish and mice. Conserved regions from the UCSC genome browser is shown below the murine RAR ChIP-seq peaks in panel (A). (C) Alignment of 9 vertebrate sequences corresponding to the second RAR sites located in skap1 gene 4th intron, showing the conservation of a DR5-like motif (blue boxes; inverse orientation) recognized by the RAR–RXR complex. Sequences highlighted in green are identical in all 9 species.
