The TRANSFAC database can be used as an encyclopedia of eukaryotic transcription factors. The target sequences and the regulated genes can be listed for each TF, which can be used as benchmark for TFBS recognition tools or as training sets for new transcription factor binding sites (TFBS) recognition algorithms.

The DNA binding sites of 519 transcription factors were evaluated. [50] Of these, 169 transcription factors (33%) did not have CpG dinucleotides in their binding sites, and 33 transcription factors (6%) could bind to a CpG-containing motif but did not display a preference for a binding site with either a methylated or unmethylated CpG.

For transcription to take place, the enzyme that synthesizes RNA, known as RNA polymerase, must attach to the DNA near a gene.Promoters contain specific DNA sequences such as response elements that provide a secure initial binding site for RNA polymerase and for proteins called transcription factors that recruit RNA polymerase.
Activator-binding sites may be located very close to the promoter or numerous base pairs away. [2] [3] If the regulatory sequence is located far away, the DNA will loop over itself (DNA looping) in order for the bound activator to interact with the transcription machinery at the promoter site. [2] [3]
The B3 DNA binding domain (DBD) is a highly conserved domain found exclusively in transcription factors (≥40 species) (Pfam PF02362) combined with other domains (InterPro: IPR003340). It consists of 100-120 residues, includes seven beta strands and two alpha helices that form a DNA-binding pseudobarrel protein fold ( SCOP 117343 ); it ...
Regulatory elements are binding sites for transcription factors, which are involved in gene regulation. [1] Cis-regulatory modules perform a large amount of developmental information processing. [1] Cis-regulatory modules are non-random clusters at their specified target site that contain transcription factor binding sites. [1]
DNA binding sites were finally confirmed in both systems [9] [10] [11] with the advent of DNA sequencing techniques. From then on, DNA binding sites for many transcription factors, restriction enzymes and site-specific recombinases have been discovered using a profusion of experimental methods.
