Abstract:
We developed a new detection system for the activation of an endoplasmic reticulum (ER) stress sensor, inositol requiring kinase 1 α (IRE1α), by evaluating dimerization of it by bimolecular fluorescence complementation (BiFC) assay. By detecting the fluorescence derived from the reconstituted cerulean, this assay system enabled us to distinguish the activation behaviors of IRE1α as to ER stress-inducing compounds.
