Translocation biosensors—versatile tools to probe protein functions in living cells

In this chapter, you will learn how to use translocation biosensors to investigate protein functions in living cells. We here present three classes of modular protein translocation biosensors tailored to investigate: (1) signal-mediated nucleo-cytoplasmic transport, (2) protease activity, and (3) protein-protein interactions. Besides the mapping of protein function, the biosensors are also applicable to identify chemicals and/or (nano) materials modulating the respective protein activities and can also be exploited for RNAi-mediated genetic screens.
