TECHNIQUE AND SCREENING METHOD FOR DETECTING REVERSIBLE PROTEIN-PROTEIN INTERACTIONS

摘要

The invention relates to methods and assays for detecting protein-protein interactions and for testing active substances in expression systems such as cells. According to the invention, protein I interacts with protein II, and a transfer of protein I into a cell compartment ensues, in which both protein I as well as protein II do not normally occur. When detecting protein II in the compartment, into which protein I was transferred, an interaction between protein I and protein II is determined.
