Promoter architecture of Drosophila genes regulated by Myocyte enhancer factor-2.

ABSTRACT: To gain understanding into the mechanisms of transcriptional activation of muscle genes, we sought to determine if genes targeted by the myogenic transcription factor Myocyte enhancer factor-2 (MEF2) were enriched for specific core promoter elements. We identified 330 known MEF2 target promoters in Drosophila, and analyzed them for for the presence and location of 17 known consensus promoter sequences. As a control, we also searched all Drosophila RNA polymerase II-dependent promoters for the same sequences. We found that promoter motifs were readily detected in the MEF2 target dataset, and that many of them were slightly enriched in frequency compared to the control dataset. A prominent sequence over-represented in the MEF2 target genes was NDM2, that appeared in over 50% of MEF2 target g
