Summary
Ribostral is a new RNA structural aligner that helps researchers evaluate basepair interactions in RNA sequences. It visualizes isostericity matrices, identifying allowed substitutions to improve alignment accuracy.
Area of Science:
- Structural biology
- Bioinformatics
- Computational biology
Background:
- RNA atomic resolution structures reveal diverse basepair interaction families and isosteric sub-families.
- Accurate RNA sequence alignment is crucial for understanding RNA structure and function.
Purpose of the Study:
- To introduce Ribostral, a user-friendly framework for analyzing RNA sequence alignments.
- To enable direct superposition of basepair isostericity matrices onto sequence alignments.
- To facilitate the identification of allowed and disallowed substitutions in RNA alignments.
Main Methods:
- Ribostral analyzes RNA sequence alignments using available atomic resolution structures.
- It superimposes isostericity matrices of observed basepairs onto sequence alignments.
- The framework visually indicates allowed and disallowed substitutions at each basepair position.
Main Results:
- Ribostral provides a clear visualization of basepair interactions within RNA sequence alignments.
- It identifies potential errors in alignments by highlighting unallowed substitutions.
- The software aids in correcting sequence alignment mistakes.
Conclusions:
- Ribostral is the first tool to directly superimpose isostericity matrices onto RNA sequence alignments.
- It enhances the accuracy of RNA sequence alignments by leveraging structural information.
- The framework supports researchers in structural biology and bioinformatics.

Ribosome Profiling
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
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...
Protein Folding Quality Check in the RER
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...
Ribosomal RNA Synthesis
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
