Protein and Protease Sensing by Allosteric Derepression

Methods Mol Biol. 2017:1596:167-177. doi: 10.1007/978-1-4939-6940-1_11.

Abstract

Peptide motifs are crucial mediators of protein-protein interactions as well as sites of specific protease activity. The detection and characterization of these events is therefore indispensable for a detailed understanding of cellular regulation. Here, we present versatile and modular sensors that allow the user to detect protease activity and protein-peptide interactions, as well as to screen for inhibitors using chromogenic, fluorescent, or luminescent output.

Keywords: Drug screening; Protease sensors; Protein-protein interaction.
