|Other Names||Serine/threonine-protein kinase/endoribonuclease IRE1, Endoplasmic reticulum-to-nucleus signaling 1, Inositol-requiring protein 1, hIRE1p, Ire1-alpha, IRE1a, Serine/threonine-protein kinase, Endoribonuclease, 3126-, ERN1 (HGNC:3449)|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|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.|
|Cellular Location||Endoplasmic reticulum membrane; Single-pass type I membrane protein|
|Tissue Location||Ubiquitously expressed. High levels observed in pancreatic tissue.|

The protein encoded by this gene is the ER to nucleussignalling 1 protein, a human homologue of the yeast Ire1 geneproduct. This protein possesses intrinsic kinase activity and anendoribonuclease activity and it is important in altering geneexpression as a response to endoplasmic reticulum-based stresssignals.
