WebAug 23, 2024 · Besides of XBP1 pre-mRNA, RNase activity of IRE1α also mediates the degradation of a select subset of cellular mRNAs, that is termed regulated IRE1-dependent decay (RIDD) . RIDD cleaved pre-mRNAs at a site different from the XBP1 spliced site, and either maintains ER homeostasis or induces apoptosis [ 21 ]. WebIRE1 is a type I transmembrane protein with a luminal sensor domain and a cytosolic effector moiety homologous to the viral infection-activated RNase, RNase L [5]. Since its identiﬁcation in 1993, IRE1 orthologs have been charac-terized in numerous species belonging to different eukary-otic phyla [6]. Further details about IRE1 orthologs and
