This information, together with previously identified operator sequences, was used to construct synthetic promoter libraries to identify those that were highly repressed. The resulting repressor ...

lad (lac repressor) which contains its own promoter and terminator sequences; lacP (promoter) which can simply be described as the RNA polymerase-binding site; and lacO (operator) which is the ...

The Methyl-CpG binding protein 2 (MeCP2) has long been considered a transcriptional repressor, given its penchant for binding histone deacetylases ... To test this, the researchers used chromatin ...
