| Abstract: | This paper expressed and purified the cytosolic fragment of human IRE1 （inositol-requiring enzyme1）, an ER transmembrane 'sensor〖KG-*9〗' protein with bacular expression system. Then the HTRF (Homogeneous Time-resolved Fluorescence) assay for IRE1 kinase was set up and optimized. Z′-factor is about 0.58 and the coefficients of variation (CV) is less than 10%, indicating the molecue-based high-throughput screening assay for IRE1 kinase inhibitor was successfully established. This work would lay a solid foundation for the discovery of IRE1 kinase inhibitor and the further research. |
