An important step in the analysis of protein function is identification of the interaction partners of each protein. The two-hybrid system has been widely used to identify and explore protein-protein interactions. By using various two-hybrid systems, numerous protein interactions that regulate apoptosis signaling have been discovered that reveal unexpected functions of cancer-relevant proteins. Methods for performing two-hybrid experiments using either yeast or mammalian cells will be described in this chapter.
