Summary
RNA maturation and degradation pathways are crucial for cellular function. RNApathwaysDB is a new online resource that systematizes data on RNA metabolic pathways and enzymes in model organisms.
Area of Science:
- Molecular Biology
- Bioinformatics
- Biochemistry
Background:
- RNA molecules undergo complex maturation processes, including splicing, modification, and polyadenylation.
- Cellular levels of mature RNAs are tightly regulated by both synthesis and degradation pathways.
- Understanding RNA metabolic pathways is essential for comprehending gene expression and cellular function.
Purpose of the Study:
- To create a comprehensive online database of RNA maturation and degradation pathways.
- To systematize information on enzymes and reactions involved in RNA metabolism.
- To provide a resource for studying RNA processing in model organisms.
Main Methods:
- Development of an online resource, RNApathwaysDB (http://iimcb.genesilico.pl/rnapathwaysdb).
- Integration of data on RNA maturation and degradation pathways, enzymes, and reactions.
- Implementation of search functionalities including keyword queries and BLAST for enzyme sequences.
- Visualization of pathways using pathway graphs, tables, and 3D 'potato models' of macromolecular complexes.
Main Results:
- RNApathwaysDB consolidates information on tRNA, rRNA, and mRNA maturation and decay pathways.
- The database covers pathways in three key model organisms: Escherichia coli, Saccharomyces cerevisiae, and Homo sapiens.
- The resource offers multiple data presentation formats, including interactive pathway visualizations and enzyme data.
- A new tool, DrawBioPath, is utilized for visualizing macromolecular complex structures.
Conclusions:
- RNApathwaysDB serves as a valuable, centralized resource for researchers studying RNA metabolism.
- The database facilitates a deeper understanding of the enzymes and pathways governing RNA processing and decay.
- This resource aids in comparative analysis of RNA metabolic pathways across different model organisms.

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,...

02:31Nuclear Export of mRNA
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...
02:51mRNA Stability and Gene Expression
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.

00:58Eukaryotic RNA Polymerases
RNA Polymerase (RNAP) is conserved in all animals, with bacterial, archaeal, and eukaryotic RNAPs sharing significant sequence, structural, and functional similarities. Among the three eukaryotic RNAPs, RNA Polymerase II is most similar to bacterial RNAP in terms of both structural organization and folding topologies of the enzyme subunits. However, these similarities are not reflected in their mechanism of action.
All three eukaryotic RNAPs require specific transcription factors, of which the...

01:53RNA Stability
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...
