RNA Editing02:23

RNA Editing

10.2K
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...

Epigenetic Regulation

4.2K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

What is Gene Expression?

12.3K
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...

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.

Area of Science:

  • Molecular Biology
  • RNA Biology
  • Genetics

Background:

  • Adenosine to inosine (A to I) editing is a crucial RNA modification process.
  • It diversifies the transcriptome by changing adenosine to inosine, which is read as guanosine.
  • Initially studied in the nervous system for coding alterations, its roles are now known to be more extensive.

Purpose of the Study:

  • To summarize the diverse roles of A to I editing.
  • To highlight recent discoveries in the field of RNA editing.
  • To explain how A to I editing generates transcriptome variability.

Main Methods:

  • Literature review of A to I editing research.
  • Analysis of studies on coding and non-coding RNA targets.
  • Examination of A to I editing's impact on splicing and immunity.

Main Results:

  • A to I editing causes amino acid changes in coding regions.
  • Editing influences RNA splicing patterns.
  • Significant A to I editing occurs in Alu elements and modulates innate immunity.

Conclusions:

  • A to I editing is a key mechanism for generating transcriptome complexity.
  • Its functions extend beyond coding recoding to regulatory roles in splicing and immunity.
  • Further research continues to uncover novel functions of A to I editing.
