 Common epigenomic profiling techniques rely on target proteins, such as the
 transcriptional regulator CTCF, binding to their respective sites on the DNA to
 isolate the sequences for sequencing. These binding sites may contain specific

 checks for the presence of these motifs in the sequences enriched from
