Insulators define independent genomic regions that are protected from the influence of distant regulatory sequences. In the 1 November EMBO Journal, Parnell and Geyer describe a novel application of the FLP recombinase to investigate the properties of two Drosophila insulators, called gypsy and scs (EMBO J 2000, 19:5864-5874). Neither insulator affected FLP recombination and protein-protein interactions at adjacent recombination sites, suggesting that gypsy and scs do not act by general inhibiti
