MyProteinNet: build up-to-date protein interaction networks for organisms, tissues and user-defined contexts

Area of Science:

• Bioinformatics
• Computational Biology
• Systems Biology

Background:

• Understanding molecular pathways requires comprehensive protein interaction data.
• Integrating context-specific protein lists with interaction databases is challenging.
• Existing data is often fragmented across multiple sources.

Purpose of the Study:

• To develop a web server for constructing context-sensitive protein interaction networks.
• To facilitate the integration of diverse protein interaction data.
• To enable analysis of protein networks in specific biological contexts.

Main Methods:

• The MyProteinNet web server aggregates data from 11 protein interaction databases.
• Users can create generic interactomes and filter them by reliability, expression, and annotation.
• The tool supports the construction of human tissue-specific interactomes using expression profiles.

Main Results:

• MyProteinNet provides users with generic and filtered interactome files.
• Network attributes and summaries are included in the output.
• The server supports 11 organisms and tens of human tissues.

Conclusions:

• MyProteinNet is a powerful tool for building up-to-date, context-specific protein interaction networks.
• It facilitates meaningful analysis of protein networks in various biological contexts.
• The server aids research in disease states and drug responses by providing integrated interactome data.
