The Drosophila eve insulator Homie promotes eve expression and protects the adjacent gene from repression by polycomb spreading.
Insulators can block the action of enhancers on promoters and the spreading of repressive chromatin, as well as facilitating specific enhancer-promoter interactions. However, recent studies have called into question whether the activities ascribed to insulators in model transgene assays actually ref...
