Protocol for analyzing protein-protein interactions by split-luciferase complementation assays in human cell lysates.
Here, we present a lysate-based split-luciferase assay for examining protein-protein interactions (PPIs) in HEK293T cell lysates, exemplified by interactions between subunits of protein phosphatase PP1. We describe steps for storing and re-using lysates, sensor design, assay setup/optimization, and high-throughput screening of compound libraries. We then detail procedures for applying the assay as a research tool to characterize the dynamics of PPIs, which we illustrate with specific examples. For complete details on the use and execution of this protocol, please refer to Claes and Bollen.1.
