TL;DR: The enhancer‐blocking protein CTCF and, most probably, the mechanism of enhancer blocking mediated by this remarkably versatile factor are conserved from Drosophila to humans.
Journal ArticleDOI
CTCF-Dependent Chromatin Boundary Element between the Latency-Associated Transcript and ICP0 Promoters in the Herpes Simplex Virus Type 1 Genome
TL;DR: The hypothesis that the 800-bp DNA in the LAT intron region works as a chromatin boundary during latency to separate active chromatin associated with the LAT promoter region from repressed chromatin in the ICP0 gene is strongly supported.
Journal ArticleDOI
Multiple Promoter Targeting Sequences exist in Abdominal-B to regulate long-range gene activation
TL;DR: The results suggest that promoter targeting is necessary for long-range enhancer-promoter communication in Abd-B, and PTS elements could be a common occurrence in large, complex genetic loci.
Journal ArticleDOI
The Promoter Targeting Sequence mediates epigenetically heritable transcription memory
TL;DR: It is found that this promoter-targeting activity is independent of an enhancer's tissue or temporal specificity, and can be remembered in all somatic cells in the absence of promoter activation.
Journal ArticleDOI
Promoter targeting sequence mediates enhancer interference in the Drosophila embryo
TL;DR: It is hypothesized that enhancer interference limits the interaction of the Abdominal-B promoter to the enhancer(s) from only one regulatory domain in a specific abdominal segment.
