Brief Introduction to Protein-Protein Interaction (PPI)

Proteins, biomolecules or macromolecules, perform a wide range of functions in organisms. Almost all of the cellular processes require that proteins specifically recognize a multitude of different interaction partners. They can carry out their roles by interacting with other molecules, including DNA, RNA, proteins and small molecules. Protein and protein interactions (PPIs), which refers to intentional physical contacts established between two or more proteins as a result of biochemical events and/or electrostatic forces. https://www.creative-proteomics.com/Services/Co-immunoprecipitation-co-IP.htm
