Figure 1From: Multiple independent evolutionary solutions to core histone gene regulationCore histone gene cis-regulatory sequence motifs and transcription factors. Experimentally verified cis-regulatory motifs and their transcription factors were taken from the literature as described in the Introduction section (see text). Sequence logos for the cis-motifs show information content (conservation) per position. Unidentified transcription factors are indicated by NI. TF, transcription factor.Back to article page
