... may be regulated by binding of multiple TFs to alternative control elements, permitting complex control of gene expression. There are about 2000 different TFs in the human organism. In many transcribed genes, there is a conserved sequence TATA box, 25-35 bp upstream of the start site. A mutation in ...
