WebThis is the first example of a class of boundary elements that share a sequence motif and a binding protein. Chromatin appears to be partitioned into chromosomal do-mains that are operationally defined by bracketing DNA re-gions called boundary elements or insulators (10; see reference 34 for a review).

Found in multicellular eukaryotes and working over distances from the promoter element of the target gene, an insulator is typically 300 bp to 2000 bp in length. Insulators contain clustered binding sites for sequence specific DNA-binding proteins and mediate intra- and inter-chromosomal interactions.
