Background

Unfolded protein response (UPR) signaling, mechanism used by eukaryotic cells to cope ER stress, is initiated by three ER-localized protein sensors: PERK (PKR-like ER kinase), ATF (activating transcription factor 6), and IRE1 alpha (inositol-requiring enzyme 1 alpha). UPR-responsive genes's transcriptional activation is regulated by ATF6 and IRE1-XBP1 pathways, and UPR serves three important functions: inhibition of protein translation to restore normal cell functions; activation of signaling to increase production of molecular chaperones involved in protein folding; and activation of signaling that leads to targeting of misfolded proteins in ER for ubiquitination and subsequent degradation; or when ER-stress is not relieved, UPR leads to apoptosis. Localized as a single-pass type I membrane protein in ER membrane, IRE1 alpha is ubiquitously expressed with high levels observed in pancreatic tissue. It undergoes autophosphorylation and gets ADP-ribosylated by PARP16 upon ER stress, which increases its kinase as well as endonuclease activities. IRE1 alpha senses unfolded proteins in the ER lumen via its N-terminal domain which leads to enzyme auto-activation and thereafter, the active endoribonuclease domain splices XBP1 mRNA to generate a new C-terminus, converting it into a potent UPR transcriptional activator. IRE1 alpha inactivation in mice has been shown to result in widespread developmental defects, leading to intra-gestational embryonic lethality and ER stress mediated cell death is responsible for several pathologies.
