Protein interactions

Definition

Protein interactions refer to the ways in which proteins communicate and bind with each other to form complexes that are crucial for various biological functions. These interactions play a vital role in cellular processes, including signal transduction, immune responses, and enzymatic activities. Understanding protein interactions is essential for developing advanced techniques in early disease detection through quantum sensing, where detecting these interactions can lead to identifying biomarkers and understanding disease mechanisms.
