The split-ubiquitin technology was developed over 20 years ago as an alternative to Gal4-based, yeast-two-hybrid methods to identify interacting protein partners. With the introduction of mating-based methods for split-ubiquitin screens, the approach has gained broad popularity because of its exceptionally high transformation efficiency, utility in working with full-length membrane proteins, and positive selection with little interference from spurious interactions. Recent advances now extend these split-ubiquitin methods to the analysis of interactions between otherwise soluble proteins and tripartite protein interactions.
