A test of insulator interactions in Drosophila [PDF]

The EMBO Journal, 2003
Insulators are a class of elements that define independent domains of gene function. The Drosophila gypsy insulator is proposed to establish regulatory isolation by forming loop domains that constrain interactions between transcriptional control elements.
