Variation of transcription factor binding sites in FUT7 promotor regions in Vertebrates. Transcription factors able to bind to the FUT7 promotor region are placed on the branches of the phylogenetic tree (horizontal bars) according to their appearance. Circles indicate the loss of DNA sites to which the transcription factors can bind. Triangles point out the split of FUT7 due to the insertion of intronic sequences into the coding region.
