Eukaryotic Transcription Activators

Eukaryotic Transcription Activators

Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

RNA Polymerase II Accessory Proteins

RNA Polymerase II Accessory Proteins

Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

Transcription Factors

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Transcription Elongation Factors

Transcription Elongation Factors

Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...

Area of Science:

Molecular Biology
Genetics
Gene Regulation

Background:

Enhancers traditionally increase gene expression by interacting with promoters.
The precise mechanisms of enhancer function, particularly transcription, are still under investigation.

Purpose of the Study:

To review recent findings on enhancer transcription and enhancer RNAs (eRNAs).
To explore the roles of eRNAs in gene regulation and enhancer function.

Main Methods:

Literature review of recent studies on enhancer transcription and eRNAs.
Analysis of existing data on enhancer-promoter interactions.

Main Results:

Enhancer transcription is prevalent and diverse, producing various enhancer RNAs (eRNAs).
eRNAs play mechanistically distinct, yet potentially overlapping, roles in enhancer function.
Transcription at enhancers influences the local chromatin landscape.

Conclusions:

Enhancer transcription and eRNAs are key factors in regulating gene expression.
Further research is needed to understand the causal links between transcription, chromatin changes, and eRNA function in long-range gene regulation.
