Biochem/physiol Actions
ER transmembrane kinase/endoribonuclease serves as an ER stress sensor that initiates the splicing of the mRNA encoding X-box–binding protein 1 (XBP-1) upon activation. Spliced XBP-1 mRNA produces homeostatic transcription factor XBP1. Under ER stress, the RNase activity of IRE1α cleaves many ER-localized mRNAs associated with apoptosis. The cytosolic motif of the activated form of IRE1α associates with the adaptor protein TRAF2 (tumor necrosis factor (TNF)–associated factor 2). This complex activates the c-Jun N-terminal kinase (JNK) signaling pathway.
Inositol-requiring enzyme-1 (IRE1) is involved in the unfolded protein response (UPR), a transcriptional program induced by endoplasmic reticulum (ER) stress. The endonuclease activity of IRE1 autoregulates its mRNA and is required for the UPR. IRE1 senses the status of luminal protein folding in the ER via its N-terminal luminal domain. Presence of unfolded and misfolded proteins leads to dimerization, trans-autophosphorylation and activation of IRE1.

General description
Inositol-requiring enzyme-1 (IRE1), consists of an N-terminal endoplasmic reticulum (ER) luminal domain, a transmembrane domain, and a C-terminal cytoplasmic region composed of a Ser/Thr protein kinase domain and a site-specific endoribonuclease (RNase) domain.
The gene ERN1 (endoplasmic reticulum to nucleus signaling 1) encodes an ER transmembrane kinase/endoribonuclease that is also referred to as IRE1α (inositol-requiring transmembrane kinase and endonuclease 1α). The serine-threonine protein kinase encoded by this gene is ubiquitously expressed in cells and tissues.

During endoplasmic reticulum (ER) stress, homeostatic signaling through the unfolded protein response (UPR) augments ER protein-folding capacity. If homeostasis is not restored, the UPR triggers apoptosis. We found that the ER transmembrane kinase/endoribonuclease (RNase) IRE1alpha is a key component of
