Structure-Based Drug Discovery of IRE1 Modulators

Résumé

IRE1α (inositol-requiring enzyme 1 alpha, referred to IRE1 hereafter) is an Endoplasmic Reticulum (ER) resident transmembrane enzyme with cytosolic kinase/RNAse activities. Upon ER stress IRE1 is activated through trans-autophosphorylation and oligomerization, resulting in a conformational change of the RNase domain, thereby promoting two signaling pathways: i) the non-conventional splicing of XBP1 mRNA and ii) the regulated IRE1-dependent decay of RNA (RIDD). IRE1 RNase activity has been linked to diverse pathologies such as cancer or inflammatory, metabolic, and degenerative diseases and the modulation of IRE1 activity is emerging as an appealing therapeutic strategy against these diseases. Several modulators of IRE1 activity have been reported in the past, but none have successfully translated into the clinics as yet. Based on our expertise in the field, we describe in this chapter the approaches and protocols we used to discover novel IRE1 modulators and characterize their effect on IRE1 activity.
