Web14 hours ago · The predicted enhancers (FDR q-value < 0.05) were used to intersect with ATAC-seq union peaks (promoter peaks excluded) and the overlapped peak set was defined as enhancer. After filtering promoters and enhancers, the remaining ATAC-seq union peak set was defined as other regulatory elements. WebFeb 26, 2015 · In particular, it is unknown whether ubiquitously active enhancers exist and how developmental and housekeeping gene regulation is separated.

WebEnhancers function as a "turn on" switch in gene expression and will activate the promoter region of a particular gene while silencers act as the "turn off" switch. Though these two regulatory elements work against each other, both sequence types affect the promoter region in very similar ways. [4] WebSummary.
