Summary
YTHDF proteins regulate gene expression via RNA methylation (m6A). Their distinct functions, driven by N-terminal sequences, control mRNA translation and degradation, impacting anticancer immunity.
Area of Science:
- Molecular Biology
- Epigenetics
- Immunology
Background:
- YTHDF proteins are key cytoplasmic 'readers' of RNA N6-methyladenosine (m6A) methylation in mammals.
- These proteins are crucial for m6A-mediated regulation, influencing mRNA translation and degradation within the cell cytosol.
- Recent studies highlight diverse functions of YTHDF proteins in fine-tuning epitranscriptome regulation.
Purpose of the Study:
- To elucidate the divergent functions of YTHDF proteins.
- To explore the mechanisms controlling YTHDF protein activity, including post-translational modifications (PTMs), subcellular localization, and protein interactions.
- To summarize the roles of YTHDF proteins in anticancer immunity and their therapeutic potential.
Main Methods:
- Analysis of amino acid sequences in YTHDF protein N-termini.
- Investigation of phase separation propensities and post-translational modifications (PTMs).
- Review of literature on YTHDF protein functions in cellular processes and cancer immunity.
Main Results:
- Divergent functions of YTHDF proteins stem from variations in their low-complexity N-terminal amino acid sequences.
- Distinct PTMs, subcellular localizations, and protein competition are identified as key regulatory mechanisms.
- YTHDF proteins play critical roles in anticancer immunity, presenting potential therapeutic targets.
Conclusions:
- YTHDF proteins exhibit versatile regulatory functions in the epitranscriptome through distinct mechanisms.
- Understanding these regulatory mechanisms is vital for exploring YTHDF proteins in cancer therapy.
- Targeting YTHDF proteins offers a promising avenue for developing novel anticancer treatments.

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...

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...

5.6K
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...

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 to it (7-Methyl...
