Phylogenetic footprinting is a technique used to identify transcription factor binding sites (TFBS) within a non-coding region of DNA of interest by comparing it to the orthologous sequence in different species. When this technique is used with a large number of closely related species, this is called phylogenetic shadowing. [1]
Transcription factor binding sites [ edit ] SBK3's promoter region was analyzed to identify predicted transcription factor binding sites (TFBS) that had high matrix similarity scores, close proximity to the transcription start site (TSS), high conservation throughout primates, and/or are a TATA-binding protein (TBP).

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.
Transcription factors (TFs) are proteins that bind DNA and thus regulate the trasncription process. The binding is sequence-specific. The binding is sequence-specific. A sequence motif [ 5 ] is a model that describes the common pattern of the DNA binding sites [ 6 ] that a particular TF prefers to bind.
ATAC-Seq analysis is used to investigate a number of chromatin-accessibility signatures. The most common use is nucleosome mapping experiments, [3] but it can be applied to mapping transcription factor binding sites, [13] adapted to map DNA methylation sites, [14] or combined with sequencing techniques. [15]
The DNA template labeled at the 3' or 5' end, depending on the location of the binding site(s). Labels that can be used are: radioactivity and fluorescence.Radioactivity has been traditionally used to label DNA fragments for footprinting analysis, as the method was originally developed from the Maxam-Gilbert chemical sequencing technique.
Chromatin Immunoprecipitation sequencing, also known as ChIP-seq, is an experimental technique used to identify transcription factor binding events throughout an entire genome. Knowing how the proteins in the human body interact with DNA to regulate gene expression is a key component of our knowledge of human diseases and biological processes.
