Where proteins connect, life takes shape.

Protein-Protein Interaction

Protein–protein interactions (PPIs) are the physical contacts formed between two or more protein molecules, allowing them to work together to carry out essential biological functions. These interactions regulate nearly every cellular process—such as signaling, metabolism, immune response, and gene expression. Understanding PPIs helps researchers uncover how cells function, how diseases develop, and how new therapeutic strategies can be designed.
