NanoLuc luciferase as a quantitative yeast two-hybrid reporter.

ABSTRACT: The yeast two-hybrid (Y2H) assay is a powerful technique to identify protein-protein interactions. However, the auxotrophic markers that are the most common Y2H reporters take several days to yield data and require subjective assessment of semiquantitative data to identify interactions. Several reporters have been developed to overcome these disadvantages, but there is still a need for a Y2H reporter that is objective, fast and able to be performed with common laboratory equipment. In this report, we replaced the ADE2 reporter in BK100 with NanoLuc luciferase to yield BK100Nano. We developed an optimized assay to measure NanoLuc activity in 96-well plates and analyzed a set of 74 pairs identified in Y2H library screens, which revealed 44 positive interactions using an unbiased cutoff based
