NettetIn an attempt to define boundary elements that could separate these gene clusters, CTCF-binding sites were searched for at the most distal DNase I-hypersensitive sites (HSs) of the mouse and human beta-globin loci. Conserved CTCF sites were found at 5'HS5 and 3'HS1 of both loci. All of these sites could bind to CTCF in vitro. NettetIn Danio rerio, the alpha- and beta-globin genes are present in two clusters: a major cluster located on chromosome 3 and a minor cluster located on chromosome 12.
