Publication Detail
A pathway sensor for genome-wide screens of intracellular proteolytic cleavage.
Abstract
Protein cleavage is a central event in many regulated biological processes. We describe a system for detecting intracellular proteolysis based on non-conventional secretion of Gaussia luciferase (GLUC). GLUC exits the cell without benefit of a secretory leader peptide, but can be anchored in the cell by fusion to beta-actin. By including protease cleavage sites between GLUC and beta-actin, proteolytic cleavage can be detected. Using this assay, we have identified regulators of autophagy, apoptosis and beta-actin cleavage.
