Organization and conservation of the miR-155 precursor gene.

<p>The structure of the human precursor gene is shown, with the location of the pre-miRNA-encoding region and promoter regions as described in the current assembly of the human genome. Comparison to the equine gene, and alignment with both human and murine genes is shown. Only predicted transcription factor binding sites conserved between humans and horses are indicated. Conservation is defined here as 70% nucleotide identity across a 100bp reading frame.
