A Nonsequencing Approach for the Rapid Detection of RNA Editing
Published on: April 21, 2022
Summary
Adenine deamination by adenosine deaminases acting on RNA (ADARs) and adenosine deaminases editing adenines in transport RNAs (ADATs) generates diverse RNA and protein forms. This RNA editing process impacts gene expression, RNA structure, and microRNA regulation in eukaryotic cells.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Context:
- Adenine deamination is a critical post-transcriptional modification in RNA.
- Adenosine deaminases acting on RNA (ADARs) and ADATs are key enzymes involved.
- This process influences RNA structure and function in eukaryotic cells.
Purpose:
- To review the current understanding of adenine deamination in RNA.
- To explore the formation of diverse RNA and protein subforms through this mechanism.
- To highlight the impact of RNA editing on gene regulation and cellular processes.
Summary:
- Adenine deamination by ADARs converts adenine to inosine (A-I editing), altering splicing, translation, and RNA secondary structure.
- ADARs also affect microRNA biogenesis and function, influencing gene silencing and RNA degradation pathways.
- ADATs deaminate adenine in tRNAs, increasing tRNA diversity and cellular regulatory capacity.
Impact:
- RNA editing diversifies the proteome and transcriptome, contributing to cellular complexity.
- Modifications by ADARs and ADATs play crucial roles in gene expression regulation.
- Understanding these mechanisms is vital for comprehending eukaryotic cell biology and potential therapeutic targets.

02:23RNA Editing
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...
01:36What is Gene Expression?
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then processed and...
01:42What is Gene Expression?
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.

02:41Chromatin Structure Regulates pre-mRNA Processing
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

Overview
01:20Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
