  • Target

    • Function

      Senses unfolded proteins in the lumen of the endoplasmic reticulum via its N-terminal domain which leads to enzyme auto-activation. The active endoribonuclease domain splices XBP1 mRNA to generate a new C-terminus, converting it into a potent unfolded-protein response transcriptional activator and triggering growth arrest and apoptosis.
    • Tissue specificity

      Ubiquitously expressed. High levels observed in pancreatic tissue.
    • Sequence similarities

      Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
      Contains 1 KEN domain.
      Contains 1 protein kinase domain.
