A 34-nt region is present in primate edn and macaque ecp promoters. (A) MISA of primate edn and ecp promoters. The grey dotted grids represent regions lacking common nucleotide sequences, and their heights represent the relative level of residue variation. The color-coded bars represent homologous regions. (B) Multiple sequence alignment of primate edn and ecp promoters by ClustalW with the conserved motifs in the 34-nt region indicated. (C) Phylogenic relationship among primate edn and ecp promoters using MEGA 3.1.
