Summary
MGEScan is a user-friendly system for identifying mobile genetic elements (transposable elements) in eukaryotic genomes. It integrates existing tools with a graphical interface and visualization capabilities, accelerating analysis on compute clusters.
Area of Science:
- Genomics
- Bioinformatics
- Computational Biology
Background:
- Existing tools for identifying long terminal repeat (LTR) and non-LTR retrotransposons lack user-friendly interfaces and data visualization features.
- Analyzing transposable elements in eukaryotic genomes requires efficient and accessible computational methods.
Purpose of the Study:
- To develop MGEScan, a user-friendly system for identifying mobile genetic elements (transposable elements) in eukaryotic genomes.
- To integrate existing retrotransposon identification programs with a graphical user interface and visualization tools.
- To accelerate the analysis of transposable elements using parallel processing techniques.
Main Methods:
- Integrated MGEScan-LTR and MGEScan-non-LTR programs into a Galaxy workflow system.
- Utilized MPI and Python threading for accelerated computation on clusters.
- Developed a graphical user interface for ease of use and data visualization.
- Implemented custom annotation track visualization in public genome browsers.
Main Results:
- Achieved a maximum speed-up of 3.26× in execution time using concurrent processing and MPI.
- MGEScan provides a user-friendly graphical interface for transposable element identification.
- The system visualizes custom annotation tracks for mobile genetic elements.
- MGEScan offers four operational modes: command line, Galaxy Toolshed, web server, and cloud deployment.
Conclusions:
- MGEScan enhances the identification and visualization of transposable elements in eukaryotic genomes.
- The system empowers researchers with accessible workflows and accelerated analysis.
- MGEScan facilitates the study of mobile genetic elements through improved usability and performance.

20.3K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

02:57DNA-only Transposons
18.2K
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.

02:13Overview of Transposition and Recombination
20.4K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

02:33Retroviruses
15.7K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

01:24Transposons
2.8K
Transposons, or "jumping genes," are small mobile genetic elements (MGEs) that range from 700 to 40,000 base pairs in length. They are found in all organisms and can move within the same chromosome or transfer to different chromosomes. In some cases, transposons can also jump between different host DNA molecules, such as plasmids or viruses, contributing to genetic variability.Barbara McClintock first discovered these mobile genetic elements in the 1940s while studying maize genetics, and she...
