PPIM

PPIM provides a database of 2,762,560 protein–protein interactions among 14,000 maize (Zea mays) proteins, integrating predicted and literature-sourced PPIs to support study of biological processes affecting traits such as yield and stress response.

Key Features:

• PPI network size: Contains 2,762,560 protein–protein interactions among 14,000 proteins.
• Data integration: Integrates accurately predicted protein–protein interactions with molecular interactions documented in the scientific literature.
• Organism focus: Concentrates specifically on maize (Zea mays) proteins and their interactions.
• Trait relevance: Provides interaction data relevant to biological processes underlying agronomic traits such as yield and stress response.

Scientific Applications:

• Study of trait biology: Investigating molecular interaction networks underlying yield and stress-response phenotypes in maize.
• Protein interaction analysis: Exploring maize protein–protein interaction topology to analyze biological processes at the protein level.
• Crop science research: Supplying a data foundation for research aimed at improving maize yield and stress resilience through molecular biology insights.

Methodology:

Integration of predicted protein–protein interactions with literature-documented molecular interaction data to assemble the maize PPI network.
