... types of components, or nodes: the genes involved in the system and the TFs that regulate their expression. Protein-protein interactions between TFs and protein-DNA interactions between TFs and their ... in DNA-binding, includ-ing SAND [28], and THAP zinc-finger [29] domains. For sev-eral of the domains unique to wTF2.0 (CP2, WH-DAC, IPT/TIG, TEA/ATTS, WT1, YL1), the genes encoding them werenot ... between 2 and 10. Interestingly, 30 TFvariants, corresponding to 25 TF genes, no longer contain aDNA binding domain. Rather than binding DNA and regulat-ing target gene expression directly, these...
