Protein-protein interaction

Protein-protein interactions occur when two or more proteins bind or work together, forming partnerships to carry out biological functions. These interactions are essential for processes like cell signaling, immune responses, and metabolic activities. Proteins recognize and bind to each other through specific regions, often involving shapes and chemical properties that fit together like puzzle pieces. These interactions are dynamic and regulated, ensuring the right proteins connect at the right time, allowing cells to coordinate complex activities efficiently and respond to changes in their environment.
