Insights

N6-Methyladenosine (m6A) is a key mRNA modification. This review details the structure, inhibitors, and functions of the m6A demethylases FTO and ALKBH5 in biological processes and diseases.

Area of Science:

  • Epigenetics
  • Molecular Biology
  • Biochemistry

Background:

  • N6-Methyladenosine (m6A) is the most prevalent internal modification in eukaryotic messenger RNA (mRNA).
  • m6A modification plays a crucial role in diverse cellular processes and homeostasis.
  • Fat mass and obesity-associated protein (FTO) and alkylation protein AlkB homolog 5 (ALKBH5) are the two known m6A demethylases.

Purpose of the Study:

  • To review the current understanding of the structure, inhibitor development, and biological functions of FTO and ALKBH5.
  • To highlight the involvement of FTO and ALKBH5 in mRNA metabolism and biological signaling pathways.
  • To discuss the role of these demethylases in the pathogenesis of cancer and other diseases.

Main Methods:

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...

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...

Eukaryotic RNA Polymerases

RNA Polymerase (RNAP) is conserved in all animals, with bacterial, archaeal, and eukaryotic RNAPs sharing significant sequence, structural, and functional similarities. Among the three eukaryotic RNAPs, RNA Polymerase II is most similar to bacterial RNAP in terms of both structural organization and folding topologies of the enzyme subunits. However, these similarities are not reflected in their mechanism of action.
All three eukaryotic RNAPs require specific transcription factors, of which the...
