MSDB: a comprehensive, annotated database of microsatellites

Area of Science:

• Genomics
• Bioinformatics
• Molecular Biology

Background:

• Microsatellites, short tandem repeats, are crucial genome markers with emerging roles in gene regulation and disease.
• Their evolutionary patterns and functional significance in eukaryotes are not fully understood.
• Existing microsatellite databases lack comprehensiveness and user-friendly analytical features.

Purpose of the Study:

• To develop and present the MicroSatellite DataBase (MSDB), the most extensive collection of microsatellite data available.
• To provide a user-friendly platform for interactive analysis and visualization of microsatellite data across multiple species.
• To facilitate research into microsatellite evolution, genome organization, and gene regulation.

Main Methods:

• Compiled >4 billion microsatellites from 37,680 eukaryotic genomes.
• Developed a web portal for data access, analysis, and visualization.
• Implemented features for interactive data exploration, filtering, and comparison across species.

Main Results:

• MSDB is the largest and most comprehensive microsatellite database to date.
• The database offers user-friendly tools for interactive data analysis and visualization.
• Data can be explored via filterable tables and comparative charts, supporting multi-species analysis.

Conclusions:

• MSDB serves as a powerful, updated resource for researchers studying microsatellites.
• Its comprehensive data and interactive features aid in understanding microsatellite evolution and function.
• The database supports research on genome organization and gene regulation involving microsatellites.
