Summary
5PSeq Explorer is a new web platform that analyzes ribosome dynamics using 5PSeq data. It provides insights into mRNA decay and ribosome behavior across many species.
Area of Science:
- Molecular Biology
- Bioinformatics
- Genomics
Background:
- Co-translational mRNA decay involves 5' to 3' exonucleases following translating ribosomes.
- This process generates 5' ribosome protected fragments (5PSeq), offering insights into ribosome dynamics.
- Systematic analysis resources for 5PSeq intermediates and associated features like ribosome stalls are limited.
Purpose of the Study:
- To develop a comprehensive platform for analyzing 5PSeq data.
- To enable in-depth exploration of ribosome dynamics in vivo.
- To facilitate the study of the interplay between mRNA decay and ribosome behavior.
Main Methods:
- Developed 5PSeq Explorer, a web-based platform.
- Utilized 773 uniformly processed 5PSeq datasets from 23 species (bacteria and Ascomycota).
- Integrated normalized counts, structured metadata, and scalable visualization tools.
Main Results:
- 5PSeq Explorer allows exploration of ribosome dynamics at codon, amino acid, and transcript levels.
- The platform provides a framework for studying the crosstalk between mRNA decay and ribosome dynamics.
- Offers both a public web interface and a Docker-based local version for accessibility and reproducibility.
Conclusions:
- 5PSeq Explorer enhances the systematic analysis of ribosome dynamics using 5PSeq data.
- The platform supports research into mRNA decay mechanisms and ribosome behavior.
- Provides a valuable, accessible resource for the scientific community.

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.

Improving Translational Accuracy
15.3K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

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,...

Translational Regulation

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...
