Protein is not an isolated biological molecule, but has a specific three-dimensional structure and interacts with other molecules (proteins, metabolites, lipids and nucleic acids) to perform functions together, such as mediating signal transduction, regulating metabolism, and energy conversion, etc. Therefore, the modularity and spatial organization of proteins are as important as their expression levels.
Proteins form a complex network by interacting with other proteins, and form a highly organized and dynamic cell system. The research of PPI is helpful to our research on diseases and the development of new drugs. In recent years, in order to analyze PPI, many research methods in vivo, in vitro and in silico have been developed, paving the way for a more comprehensive and systematic study of PPI in the future.
