Insights

N6-methyladenine (6 mA) is an epigenetic mark found in eukaryotes, though its prevalence and function remain debated. This review details detection methods, occurrence, and roles of 6 mA in eukaryotes, highlighting research gaps.

Area of Science:

  • Epigenetics
  • Molecular Biology
  • Genomics

Background:

  • DNA methylation, particularly 5-methylcytosine (5mC), is well-studied.
  • N6-methyladenine (6 mA) was initially identified in prokaryotes.
  • Recent advances reveal 6 mA in diverse eukaryotes, but its significance is debated due to low abundance and detection challenges.

Purpose of the Study:

  • To review N6-methyladenine (6 mA) detection methods in eukaryotes.
  • To summarize the current understanding of 6 mA prevalence and functions in eukaryotes.
  • To identify knowledge gaps and future research directions for 6 mA in eukaryotes.

Main Methods:

  • Literature review of 6 mA detection technologies.
  • Compilation of existing reports on 6 mA occurrence in eukaryotic organisms.
  • Analysis of potential enzymes (methyltransferases, demethylases) and proteins involved in 6 mA modification.

Main Results:

  • Overview of advantages and disadvantages of various 6 mA detection techniques.
  • Summary of 6 mA presence across eukaryotes (protozoans, metazoans, plants, fungi).
  • Discussion of potential 6 mA pathway components and documented biological roles.

Conclusions:

  • The prevalence and biological significance of 6 mA in eukaryotes require further investigation.
  • Improved detection technologies are crucial for advancing 6 mA research in eukaryotes.
  • Understanding 6 mA's role is essential for a comprehensive view of eukaryotic epigenetics.

RNA Editing02:23

RNA 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...

Pre-mRNA Processing: Modification of pre-mRNA Ends01:35

Pre-mRNA Processing: Modification of pre-mRNA Ends

In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a cap to the 5' end of the growing transcript. In this process, a 5' phosphate is replaced by modified guanosine that has a methyl group attached (7-methyl guanosine). This 5' cap helps...

Transfer RNA Synthesis02:36

Transfer RNA Synthesis

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

RNA Stability01:53

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Histone Modification02:32

Histone Modification

The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...
