Inositol-requiring enzyme 1 (IRE1; EC is an endoplasmatic reticulum (ER) transmembrane sensor that activates the unfolded protein response (UPR) through a cytoplasmic kinase domain and an RNase domain to maintain the ER and cellular function[1]. On ER stress, IRE1 RNase is activated through conformational change, autophosphorylation, and higher-order oligomerization. The active endoribonuclease domain splices XBP1 mRNA to generate a new C-terminus, converting it into a potent unfolded-protein response transcriptional activator and triggering growth arrest and apoptosis[2].
