Abstract
Enhancers are noncoding regulatory elements that instruct spatial and temporal specificity of gene transcription in response to a variety of intrinsic and extrinsic signals during development. Although it has long been postulated that enhancers physically interact with target promoters through the formation of stable loops, recent studies have changed this static view: sequence-specific transcription factors (TFs) and coactivators are dynamically recruited to enhancers and assemble so-called transcription hubs. Dynamic assembly of transcription hubs appears to serve as a key scaffold to integrate regulatory information encoded by surrounding genome and biophysical properties of transcription machineries. In this review, we outline emerging new models of transcriptional regulation by enhancers and discuss future perspectives.
期刊介绍：
Trends in Cell Biology stands as a prominent review journal in molecular and cell biology. Monthly review articles track the current breadth and depth of research in cell biology, reporting on emerging developments and integrating various methods, disciplines, and principles. Beyond Reviews, the journal features Opinion articles that follow trends, offer innovative ideas, and provide insights into the implications of new developments, suggesting future directions. All articles are commissioned from leading scientists and undergo rigorous peer-review to ensure balance and accuracy.
