All metabo- lism or vital activities of living organisms are attributed to the interactions of numbers of biomolecules, including protein-protein interactions. Cell growth and differentia- tion, development and generation or regeneration of tissue, and the occurrence of or protection against various diseases are triggered, conducted, and maintained by the complex sequential interactions among molecules both inside and outside the cells....
