Summary
RNA FRABASE is a novel web tool for searching 3D RNA fragments in RNA structures. It efficiently analyzes RNA sequences and structures, aiding 3D structure modeling and analysis.
Area of Science:
- Structural Biology
- Bioinformatics
- Computational Biology
Background:
- Analyzing three-dimensional (3D) RNA structures is crucial for understanding RNA function.
- Existing tools may lack comprehensive capabilities for searching specific RNA fragments within large structural datasets.
- The development of efficient search engines is needed for RNA structure analysis and modeling.
Purpose of the Study:
- To introduce RNA FRABASE, a web-accessible engine for automated searching of user-defined 3D RNA fragments.
- To provide a tool for analyzing RNA sequences and secondary structures in the context of 3D structural data.
- To facilitate 3D structure modeling by enabling efficient retrieval of RNA fragments.
Main Methods:
- Development of a relational database containing RNA sequences, secondary structures (dot-bracket notation), and 3D structural information.
- Implementation of an efficient search algorithm for identifying 3D RNA fragments based on user queries.
- Inclusion of data on nucleotide residues, torsion angles, sugar pucker parameters, and base pairs.
- Integration of advanced query filters for modified residues, experimental methods, and conformational parameters.
Main Results:
- The RNA FRABASE database, as of August 2007, contains data from 1065 Protein Data Bank (PDB)-deposited RNA structures.
- The database includes atom coordinates, calculated conformational parameters, and base-pairing information for RNA fragments.
- Search results provide direct download access to PDB-format files for visualization and further analysis.
- The search algorithm demonstrates high efficiency in retrieving relevant 3D RNA fragments.
Conclusions:
- RNA FRABASE is a valuable and efficient resource for researchers studying RNA 3D structures.
- The tool simplifies the process of searching and analyzing specific RNA fragments, supporting 3D structure modeling.
- The database is regularly updated and freely accessible, promoting wider use in the scientific community.

03:21RNA-seq
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Overview
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.

02:27Nonsense-mediated mRNA Decay
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,...

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.
