Figure 7. Archetypal cross-species gene regulatory region models of undifferentiated and differentiated gene clusters. These models incorporate transcription response element (TREs) that were found to be over-represented in results of both the human and chicken, as well as either the mouse or rat, promoter analysis and interaction network toolset (PAINT) analysis. TSS represents transcriptional start site.
