Summary
This summary is machine-generated.Regulatory non-coding RNAs (ncRNAs), including enhancer RNAs (eRNAs) and PROMoter uPstream Transcripts (PROMPTs), play crucial roles in cellular functions by influencing transcription and chromatin structure.
Area Of Science
- Molecular Biology
- Genetics
- Epigenetics
Background
- Regulatory non-coding RNAs (ncRNAs) produced by RNA Polymerase II (Pol II) are increasingly recognized for their roles in cellular processes.
- Thousands of ncRNAs originate from regulatory elements like enhancers and promoters, impacting development, cellular programming, transcription, and genomic stability.
Purpose Of The Study
- To review the mechanisms of regulatory element-associated ncRNAs, focusing on enhancer RNAs (eRNAs) and PROMoter uPstream Transcripts (PROMPTs).
- To contextualize these mechanisms within RNA processing and degradation pathways.
- To summarize recent findings on how ncRNAs function locally or distally to influence cellular fate.
Main Methods
- Literature review of recent findings on regulatory element-associated ncRNAs.
- Analysis of mechanisms involving RNA processing, degradation, and function.
- Synthesis of a model for ncRNA-mediated regulation of transcription and chromatin structure.
Main Results
- ncRNAs, particularly eRNAs and PROMPTs, are short-lived molecules involved in regulating transcription and chromatin.
- These ncRNAs can act locally at their sites of production or exert functions at distant genomic locations.
- Mechanisms include both immediate post-transcriptional effects and roles mediated by stabilized ncRNAs.
Conclusions
- A converging model suggests ncRNAs significantly influence cellular fate by modulating transcription and chromatin structure.
- These regulatory roles may involve interactions with factors participating in 3D nuclear organization.
- Understanding ncRNA mechanisms provides insights into fundamental cellular processes and potential therapeutic targets.

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
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...
