Super enhancers-Functional cores under the 3D genome

Cell Prolif. 2021 Feb;54(2):e12970. doi: 10.1111/cpr.12970. Epub 2020 Dec 17.

Abstract

Complex biochemical reactions take place in the nucleus all the time. Transcription machines must follow the rules. The chromatin state, especially the three-dimensional structure of the genome, plays an important role in gene regulation and expression. The super enhancers are important for defining cell identity in mammalian developmental processes and human diseases. It has been shown that the major components of transcriptional activation complexes are recruited by super enhancer to form phase-separated condensates. We summarize the current knowledge about super enhancer in the 3D genome. Furthermore, a new related transcriptional regulation model from super enhancer is outlined to explain its role in the mammalian cell progress.

Keywords: 3D genome; biological processes; phase-separated condensates; super enhancer; transcription model.
