Genomic locations of TF clusters. Clusters of TF genes are shown on an ideogram representation of the 24 human chromosomes. As shown in the legend at the top right, the four canonical Hox gene clusters are shown in blue, the previously described chromosome 19 zinc finger gene clusters are shown in green, and putative TF clusters identified in this study are shown in red. The number in parentheses following each in the legend indicates the number of each type of cluster shown in this figure. Clusters containing known genes are labeled. Labels are not included for hypothetical and unnamed genes, and so clusters consisting entirely of these are unlabeled. For a list of the genes comprising each cluster, see Supplemental materials.
