What is the function of the enhancer region in eukaryotic DNA?

In addition to promoter sequences, enhancer regions help augment transcription. Enhancers can be upstream, downstream, within a gene itself, or on other chromosomes. Specific transcription factors bound to enhancer regions may either increase or prevent transcription.

What is the enhancer region in transcription?

In genetics, an enhancer is a short (50–1500 bp) region of DNA that can be bound by proteins (activators) to increase the likelihood that transcription of a particular gene will occur. These proteins are usually referred to as transcription factors.

How are enhancers involved in eukaryotic transcription?

Enhancers increase the rate of transcription of genes, while repressors decrease the rate of transcription.

What is an enhancer in eukaryotic cells?

An enhancer (transcription enhancer, transcriptional enhancer) is a regulatory DNA segment of about 200 base pairs that is typically found in multicellular eukaryotes. It can strongly stimulate (“enhance”) the transcription of a linked transcription unit, i.e. it acts in cis.

What are enhancers and promoters?

An enhancer is a sequence of DNA that functions to enhance transcription. A promoter is a sequence of DNA that initiates the process of transcription. A promoter has to be close to the gene that is being transcribed while an enhancer does not need to be close to the gene of interest.

What are promoters and enhancers?

Is enhancer a promoter?

What is the relationship between the promoter and enhancer regions?

How do you find the enhancer region of a gene?

The only way to really identify whether a given region is a bona fide enhancer for your gene of interest is through experimental validation (e.g. CRISPR perturbation). To identify candidate enhancers, typically H3K27ac ChIP-Seq and/or ATAC-seq (chromatin accessibility) signal is used.
