Gene3D is a protein domain database that now includes functional families and enhanced visualization tools. This protein domain assignment resource aids in understanding molecular function, structure, and evolution across multiple genomes.
Area of Science:
- Bioinformatics
- Structural Biology
- Genomics
Background:
- Gene3D is a comprehensive database for protein domain assignments, integrating data from major sequence databases and the CATH structural database.
- It utilizes profile hidden Markov models (HMMs) derived from CATH superfamilies for domain prediction and assignment.
- The database facilitates the integration of diverse protein family and function information, enabling complex analyses of molecular function, structure, and evolution.
Purpose of the Study:
- To introduce updates to the Gene3D database, including a new domain functional family (FunFam) level and expanded interaction data.
- To present a revamped website with improved search functionalities and advanced visualization tools for multi-genome scale data interpretation.
- To enhance the usability and analytical capabilities of Gene3D for researchers studying protein domains and their evolutionary relationships.
Main Methods:
- Protein domain assignments are directly mapped from CATH database structures or predicted using profile HMMs.
- Integration of multiple protein family and function databases to establish cross-references.
- Development of a new website featuring simplified searching, advanced filtering, and Cytoscape Web-based visualization tools.
Main Results:
- Gene3D now incorporates a domain functional family (FunFam) classification below the superfamily level.
- Enhancements to interaction data and the introduction of new visualization tools for network analysis.
- A revamped website offers simplified search, sophisticated filtering, and visualization of protein-protein interactions, domain composition differences, and taxonomic distributions.
Conclusions:
- The updated Gene3D database and website provide powerful tools for the visualization and interpretation of large-scale genomic and proteomic data.
- The new features facilitate deeper insights into protein domain function, evolution, and interactions across various species.
- Gene3D continues to be a valuable resource for researchers in bioinformatics and structural biology, supporting comparative genomics and evolutionary studies.
