Figure 4From: An arthropod cis-regulatory element functioning in sensory organ precursor development dates back to the CambrianArrangement of transcription factor binding sites in the UTR of the arthropod ase -like genes. Note that the SOPE covers a larger area in D. pulex (882 bp) and in S. maritima (1,052 bp) compared to D. melanogaster (297 bp), T. castaneum (247 bp) and C. salei (246 bp). See text for details. Yellow, E box; green, β box; pink, α box; blue, N box. Dm, D. melanogaster; Tc, T. castaneum; Dp, D. pulex; Cs, C. salei; Sm, S. maritima.Back to article page
