Summary
Researchers developed new methods to discover N6-methyladenosine (m6A) reader proteins and map their binding sites on RNA. This advances understanding of m6A regulation in cells.
Area of Science:
- Molecular Biology
- Epigenetics
- RNA Biology
Background:
- N6-methyladenosine (m6A) is a crucial reversible RNA modification impacting mRNA fate.
- m6A function relies on specific "reader" proteins that bind m6A-modified RNA.
Purpose of the Study:
- To present novel methods for identifying m6A reader proteins.
- To describe techniques for mapping m6A reader binding sites transcriptome-wide.
Main Methods:
- RNA pull-down assay to identify novel m6A reader proteins from known m6A sites.
- Immunoprecipitation-based sequencing to map reader-bound m6A sites across the transcriptome.
Main Results:
- A described RNA pull-down method enables the discovery of new m6A reader proteins.
- Combined immunoprecipitation-sequencing methods allow for transcriptome-wide identification of m6A reader targets.
Conclusions:
- The developed methods facilitate the discovery of new m6A reader proteins and their targets.
- Further insights into m6A regulatory mechanisms and functions can be gained through these discoveries.

RNA Editing
10.0K
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...

Ribosome Profiling
4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Nonsense-mediated mRNA Decay
12.0K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Leaky Scanning
5.8K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

pre-mRNA Processing
57.8K
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...
