Widespread Increase in Enhancer—Promoter Interactions during Developmental Enhancer Activation in Mammals

Z Chen, V Snetkova, G Bower, S Jacinto, B Clock… - BioRxiv, 2022 - biorxiv.org
Remote enhancers are thought to interact with their target promoters via physical proximity,
yet the importance of this proximity for enhancer function remains unclear. Although some …

Hunchback is counter-repressed to regulate even-skipped stripe 2 expression in Drosophila embryos

BJ Vincent, MV Staller, F Lopez-Rivera… - PLoS …, 2018 - journals.plos.org

Ciona Brachyury proximal and distal enhancers have different FGF dose-response relationships

MJ Harder, J Hix, WM Reeves, MT Veeman - PLoS Genetics, 2021 - journals.plos.org
Many genes are regulated by two or more enhancers that drive similar expression patterns.
Evolutionary theory suggests that these seemingly redundant enhancers must have …
