Abstract

Introduction:

Agricultural animals are essential for global food production and sustainable agriculture. Improving disease resistance and economically important traits is critical for ensuring food security. Proteome-wide protein-protein interactions (PPIs), termed as interactomes, underlie key biological processes in cells, making them critical for deciphering the genome-phenome relationship. However, species-specific PPI resources remain limited for most agricultural animals.

Objectives:

Motivated by the rapid development of deep learning and breakthroughs in AI-driven protein structure prediction, we attempted to develop an integrated structural interactome resource for agricultural animals.

Methods:

We predicted species-specific interactomes through an integrative prediction pipeline that combines interolog mapping, domain-domain interaction inference, and deep learning. The 3D complex structures of all predicted PPIs were further generated using ESMFold.

Results:

We established AASIA (Agricultural Animals Structural Interactome Atlas; https://aasia.zzdlab.com), a user-friendly database comprising 410,421 high-confidence PPIs and corresponding complex structures across five key species, including Anas platyrhynchos, Bos taurus, Gallus gallus, Ovis aries, and Sus scrofa.

Conclusions:

AASIA provides the first proteome-scale structural interactome resource for five key agricultural animals. By integrating interaction prediction with structural modeling, it enables mechanistic insight into agriculturally relevant traits and supports applications in variant interpretation, multi-omics integration, and molecular breeding.

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...

Protein Organization

Protein Organization

Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence.
