Genomic organization of gypsy chromatin insulators in Drosophila melanogaster.

Genetics - 1 Apr 2006

Ramos Edward, Ghosh Dolanchanpa, Baxter Ellen, Corces Victor G

Abstract excerpt

Chromatin insulators have been implicated in the regulation of higher-order chromatin structure and may function to compartmentalize the eukaryotic genome into independent domains of gene expression. To test this possibility, we used biochemical and computational approaches to identify gypsy-like genomic-binding sites for the Suppressor of Hairy-wing [Su(Hw)] protein, a component of the gypsy insulator. EMSA and...
