The Phyre2 web portal for protein modeling, prediction and analysis

Area of Science:

• Biochemistry
• Bioinformatics
• Structural Biology

Background:

• Protein structure and function are critical for biological processes.
• Accurate prediction of protein models aids in understanding biological mechanisms.
• Analysis of mutations is essential for disease research and drug development.

Purpose of the Study:

• To introduce Phyre2, an updated web server for protein structure, function, and mutation analysis.
• To provide biologists with an intuitive interface to advanced protein bioinformatics tools.
• To guide users in interpreting protein models, domain composition, and quality.

Main Methods:

• Utilizes advanced remote homology detection for 3D model building.
• Predicts ligand binding sites and analyzes the effects of amino acid variants (e.g., nonsynonymous SNPs).
• Offers a user-friendly interface for detailed result interpretation.

Main Results:

• Phyre2 provides 3D protein models, predicts ligand binding sites, and analyzes mutation impacts.
• The server guides users through secondary and tertiary structure interpretation, domain composition, and model quality.
• Additional tools facilitate genome-wide structure searches and automated modeling for challenging proteins.

Conclusions:

• Phyre2 offers a comprehensive and accessible platform for protein bioinformatics analysis.
• The tool empowers biologists with state-of-the-art methods for structure prediction and variant analysis.
• Phyre2 enhances the understanding of protein function and the impact of genetic variations.
