Insulators: A “Safety Guard” For Genome Stability In Drosophila Melanogaster, Ran An

Doctoral Dissertations

Chromatin insulators are DNA-protein complexes that assist in the formation of chromatin loop structures by mediating long-range contacts between distant sites, which regulate proper organization of the chromatin fiber within the tridimensional space of the nucleus. It is considered that this function of insulators is required for the regulation of gene expression during development and in differentiated cells. This thesis focuses specifically in the Suppressor of Hairy wing [Su(Hw)] insulator of Drosophila and its associated proteins, and explores the possibility that chromatin insulators are not only significant for regulation of gene expression, but are also essential for DNA replication and …
