Assembles a collection of molecular tools for examining and characterizing protein-protein, protein-DNA, and protein-RNA interactions. This work also provides methods for dealing with the problem of artifacts and false positives and for identifying the interacting partners in biological systems, including the SMAD and nuclear receptor pathways.

Many, if not all, essential biological processes require selective interactions between proteins. Complex signaling systems require sequential, ordered protein-protein interactions at essentially all levels of the signaling cascade. For example, peptide hormones interact with selective membrane receptor proteins, and autophosphorylation of the receptor then recruits other key regulatory proteins that initiate kinase cascades in which each phosphorylation event requires selective recognition of the protein substrate. The ultimate signaling effect, in many cases, is the regulation of RNA polymerase II-directed transcr- tion in the nucleus, a process that involves numerous, multiprotein complexes important for transcription initiation, elongation, termination, and reinitiation. Defining, characterizing, and understanding the relevance of these protein- protein interactions is an arduous task, but substantial inroads have been made over the past 20 years.
The development of more recent methodologies, such as mammalian expression systems, immunopurification schemes, expression cloning strategies, surface plasmon resonance (BiaCore), and nanosequencing technologies, has contributed a wealth of new insights into these complex multiprotein mechanisms and clearly accelerated the discovery process. Arguably, the yeast two-hybrid system has been one of the predominant and most powerful tools in this discovery process.
