Summary
This study introduces eRNA-IDO, a computational platform for identifying enhancer RNAs (eRNAs) and their interactions. It aids in understanding eRNA functions and gene regulation.
Area of Science:
- Genomics
- Computational Biology
- Molecular Biology
Background:
- Enhancer RNAs (eRNAs) are increasingly recognized for their roles in gene regulation.
- The interactions and functions of eRNAs are not yet fully understood.
- Mechanistic research on eRNAs requires specialized tools.
Purpose of the Study:
- To develop the first integrative computational platform, eRNA-IDO, for human eRNA analysis.
- To enable identification, interactome discovery, and functional annotation of eRNAs.
- To facilitate research into eRNA biogenesis and function.
Main Methods:
- eRNA-IDO consists of two modules: eRNA-ID for eRNA identification and eRNA-Anno for functional annotation.
- eRNA-ID utilizes eight enhancer markers for flexible enhancer region customization.
- eRNA-Anno analyzes eRNA interactomes using prebuilt or user-defined networks (GTEx, TCGA, omics-based).
Main Results:
- eRNA-ID successfully identifies eRNAs from de novo assembled transcriptomes.
- eRNA-Anno provides cell-/tissue-specific functional annotations for known and novel eRNAs.
- The platform integrates diverse network data for comprehensive eRNA interactome analysis.
Conclusions:
- eRNA-IDO is a valuable computational tool for advancing eRNA research.
- The platform facilitates the study of eRNA roles in gene regulation.
- eRNA-IDO is freely available to the research community.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

6.1K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

9.1K
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...

02:42Eukaryotic Transcription Activators
10.9K
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...
