Supplementary Figure 1. Murine and human GATA2 promoter alignment shows highly conserved regions. Brackets delimit the highly conserved regions in both genomes, as graphics obtained from ECR Browser show: large areas marked in red indicate highly similar intergenic sequences, repetitive sequences in green, exonic sequences in yellow, and intronic sequences in salmon color. Horizontal axis represents base positions in the genome and the vertical axis represents the percentage identity between the human and mouse genomes. GATA2 binding sites are indicated in red within the brackets, and they were located using the TFSearch, Match and MatInspector transcription factor binding site finder algorithms. Comparison of GATA2 binding sites between both genomes and several surrounding nucleotides is shown in the middle, where GATA2 binding site core sequences are shown in italic and underlined. Two GATA2 binding sites at -2.8 belonged to a highly conserved region spanning 389 bp, with 87.7% homology with the human GATA2 promoter. Similarly, other two GATA2 binding sites at -1.8 were located within a 282 bp region with 75.5% homology. Additionally, a third 142 bp region was taken into account containing the -2992 GATA2 binding site, which showed 68.3% homology.
