Promoter and enhancer regions翻译
WebApr 13, 2024 · In this review, Uyehara and Apostolou discuss recent findings and remaining gaps regarding the mechanisms that control enhancer-promoter communication in the context of the 3D genome. They also focus on 3D hubs that involve multiple enhancers and promoters and speculate on their role in gene regulation and their organizational principles.

WebOct 25, 2024 · Enhancer regions are binding sequences, or sites, for specific transcription factors. When a protein transcription factor binds to its enhancer sequence, the shape of the protein changes, allowing it to interact with proteins at the promotor site.
WebEnhancer regions are binding sequences, or sites, for transcription factors. When a DNA-bending protein binds, the shape of the DNA changes (Figure 16.10). This shape change allows for the interaction of the activators bound to the enhancers with the transcription factors bound to the promoter region and the RNA polymerase. WebHowever, since the enhancer region may be distant from the promoter, the DNA must bend to allow the proteins at the two sites to come into contact. DNA bending proteins help to bend the DNA and bring the enhancer and promoter regions together . This shape change allows for the interaction of the specific activator proteins bound to the ...
