Protein Interactions

Proteins interact with each other in cells to carry out the majority of essential biological functions. Protein interactions play an essential role in defining how proteins work and how cells respond to external stimuli and conditions. These interactions are determined by the affinity of proteins for one another, which are regulated by the sequence of amino acids that form each protein. Protein interactions can be studied experimentally to gain insight into the mechanisms of diseases and other biological processes. Protein interactions can also be used to develop targeted therapeutic treatments, such as drugs and gene therapies, that selectively intervene with specific diseased pathways.
