When the ER stress-induced unfolded protein response (UPR) is activated, the X-box binding protein 1 (XBP1) mRNA is spliced by inositol-requiring enzyme-1α (IRE1α) to produce the spliced form of XBP1 (sXBP1). In the present study, we found that sXBP1 mRNA in the cell may be incorporated into the exosomes and was released extracellularly. Spliced form of XBP1 mRNA was incorporated into the exosomes of HEK293T cells, which overexpress IRE1α. We found that one of the ER stress signal-induced transcripts, sXBP1, was incorporated into the exosomes. Our results suggest that exosomes may play a vital role in the extracellular release of ER stress signals. |

P300 increases the acetylation and protein stability of XBP1s, and enhances its transcriptional activity, whereas SIRT1 deacetylates XBP1s and inhibits its transcriptional activity.. The mRNA encoding the active spliced form of XBP1 (XBP1s) is generated from the unspliced form by IRE1 (inositol-requiring enzyme 1) during the UPR. |

ATF6 and XBP1 are transcription factors activated specifically in response to endoplasmic reticulum (ER) stress. Three cis-acting elements capable of binding to ATF6, XBP1 or both have been identified to date, namely ER stress-response element (ERSE), unfolded protein response element (UPRE) and ERSE-II. ERSE controls the expression of ER-localized molecular chaperones such as BiP that can refold unfolded proteins in the ER; transcription from ERSE is fully activated by ATF6 even in the absence of XBP1. In contrast, transcription from UPRE depends solely on XBP1 and it has been suggested that UPRE may control the expression of components of the ER-associated degradation system that can degrade unfolded proteins in the ER. |

Upon activation by oligomerization and autophosphorylation, the cytosolic RNase domain of IRE1 mediates an unconventional splicing of the mRNA of X-box-binding protein 1 (XBP1). The spliced and frameshifted transcript encodes XBP1S, a bZIP transcription factor inducing the expression of numerous UPR effector genes that enhance ER folding capacity. |
