The first examples of insulators in vertebrates was seen in the chicken β-globin locus, cHS4. cHS4 marks the border between the active euchromatin in the β-globin locus and the upstream heterochromatin region that is highly condensed and inactive. The cHS4 insulator acts as both a barrier to chromatin-mediated silencing via heterochromatin spreading, and blocks interactions between enhancers and promoters. A distinguishing characteristic of cHS4 is that it has a repeti… WebThe genes that a eukaryotic cell turns "on" largely determine its identity and properties. For instance, a photoreceptor cell in your eye can detect light because it expresses genes for light-sensitive proteins, as well as as genes for neurotransmitters that allow signals to be relayed to the brain.
