WebDiagram illustrating how a repressor works. A repressor protein binds to a site called on the operator. In this case (and many other cases), the operator is a region of DNA that overlaps with or lies just downstream of the RNA polymerase binding site (promoter). That is, it is in between the promoter and the genes of the operon. WebSep 24, 2024 · INTRODUCTION. Enhancers are distal regulatory DNA regions essential for the precise spatiotemporal control of gene expression ().They are bound by transcription factors (TFs) and activate gene expression through interaction with the gene promoter in a cell-type-specific manner ().Sequence variants within enhancers can alter transcription …
