No protein is an island. They're linked by complex networks, and many cellular processes – transcription, translation, mitosis, and motility, to name but a few – are the work of complex macromolecular machines. Researchers keen to figure out how proteins interact were for many years hamstrung by relatively crude, and labor-intensive, analytical tools. Then, in the late-1980s, a new option emerged: the yeast two-hybrid (Y2H) assay.
