Summary
The RNA Editing Database (REDIdb) is a new resource for RNA editing events, including substitutions, insertions, and deletions across organisms. It offers graphical and alignment views for easy identification of editing sites.
Area of Science:
- Bioinformatics
- Molecular Biology
- Genomics
Background:
- RNA editing is a post-transcriptional modification that alters the information encoded by RNA.
- Understanding RNA editing events is crucial for comprehending gene expression and regulation.
- Existing resources for RNA editing information are fragmented and lack comprehensive data integration.
Purpose of the Study:
- To develop and launch the RNA Editing Database (REDIdb), a centralized, interactive, web-based platform.
- To curate and store a comprehensive collection of RNA editing events from diverse organisms.
- To provide user-friendly tools for browsing, visualizing, and submitting RNA editing data.
Main Methods:
- Designed an interactive, web-based relational database (REDIdb).
- Integrated experimental (in vitro) and computational (in silico) data for RNA editing events.
- Developed graphical and alignment visualization tools for sequence and editing site analysis.
- Implemented a user registration system for secure data submission.
Main Results:
- The initial version of REDIdb stores 9964 RNA editing events.
- The database includes data from both fully and partially sequenced DNA molecules.
- Features include detailed flat-file records with characteristics, feature tables, and sequence zones.
- Interactive tools allow graphical display of sequences and alignments with highlighted editing sites.
Conclusions:
- REDIdb provides a valuable, centralized resource for RNA editing research.
- The database facilitates the identification and analysis of RNA editing events across a wide range of organisms.
- REDIdb supports community contributions through a user-friendly submission system, promoting collaborative research in RNA editing.

02:23RNA Editing
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...
02:53CRISPR and crRNAs
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

02:15Experimental RNAi
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
01:59CRISPR
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...
01:32RNA Splicing
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
01:23RNA Structure
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.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...
