An active enhancer regulatory region of DNA is enabled to interact with the promoter DNA region of its target gene by the formation of a chromosome loop. This can initiate messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The loop is stabilized by one architectural ...

Acetylation is usually linked to the upregulation of genes. This is the case in H3K27ac which is an active enhancer mark. It is found in distal and proximal regions of genes. It is enriched in Transcriptional start sites (TSS). H3K27ac shares a location with H3K27me3 and they interact in an antagonistic manner.
The gene contains an active enhancer region proceeding the coding sequence (CDS) and three histone H3 lysine 4 mono-methylation human embryonic stem cell (hESC) sites marking poised or active enhancers throughout C15orf62. H3K4me1 facilitates promoter-enhancer interactions and gene activation during embryonic stem cell differentiation. [16]
STARR-seq (short for self-transcribing active regulatory region sequencing) is a method to assay enhancer activity for millions of candidates from arbitrary sources of DNA. It is used to identify the sequences that act as transcriptional enhancers in a direct, quantitative, and genome-wide manner.
An active enhancer regulatory region is enabled to interact with the promoter region of its target gene by formation of a chromosome loop. This can initiate messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The loop is stabilized by one architectural protein anchored ...

H3K4me1 fine-tunes the enhancer activity and function rather than controls. [4] H3K4me1 is put down by KMT2C (MLL3) and KMT2D (MLL4) [6] LSD1, and the related LSD2/KDM1B demethylate H3K4me1 and H3K4me2. [7] Marks associated with active gene transcription like H3K4me1 and H3K9me1 have very short half-lives. [8]
