Human matrix attachment regions insulate transgene expression from chromosomal position effects in Drosophila melanogaster.

Abstract excerpt

Germ line transformation of white- Drosophila embryos with P-element vectors containing white expression cassettes results in flies with different eye color phenotypes due to position effects at the sites of transgene insertion. These position effects can be cured by specific DNA elements, such as the Drosophila scs and scs' elements, that have insulator activity in vivo. We have used this system to determine...
