title: [Conservative E(y)2/Sus1 protein interacts with the Su(Hw)-dependent insulators in Drosophila].
abstract: Insulators are regulatory elements having two properties. First, they are able to disturb the interaction between promoters and enhancers/silencers. Second, they are able to block distribution of the heterochromatin. The best-studied are the Su(Hw)-dependent insulators of Drosophila melanogaster, activity of which is determined by the Su(Hw) protein. In this study it was demonstrated that novel, evolutionary conservative transcription factor E(y)2/Sus1 interacted with the Su(Hw) zinc-finger domain and was present in the protein complex, associated with the Su(Hw)-dependent insulators.
