Background
XBP1 (X-box-binding protein 1) is master transcription factor of endoplasmic-reticulum-stress UPR (unfolded-protein-response) pathway. Accumulation of misfolded proteins activates IRE1, which mediates XBP1-mRNA splicing to generate potent active spliced isoform XBP1-s. Nuclear XBP1-s up-regulates ER-folding and ER-associated-degradation transcripts to resolve ER stress. Unspliced XBP1-u exhibits minimal transcriptional activity.
