Primary Accession O75460
Reactivity Human
Host Mouse
Clonality Monoclonal
Clone Names 9F2
Isotype IgG1
Calculated MW 109kDa
Description The protein encoded by this gene is the ER to nucleus signalling 1 protein, a human homologue of the yeast Ire1 gene product. This protein possesses intrinsic kinase activity and an endoribonuclease activity and it is important in altering gene expression as a response to endoplasmic reticulum-based stress signals.
Immunogen Purified recombinant fragment of human ERN1(aa282-433) expressed in E. Coli.
Formulation Ascitic fluid containing 0.03% sodium azide.
Additional Information
Gene ID 2081
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, 3.1.26.-, ERN1 (HGNC:3449)
Dilution WB~~1/500 - 1/2000
IHC~~1/500 - 1/2000
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsERN1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name ERN1 (HGNC:3449)
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.
