Rabbit Anti-IRE1/FITC Conjugated antibody
background:
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. [provided by RefSeq, Jul 2008]
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 SLCterminus, converting it into a potent unfolded-protein response transcriptional activator and triggering growth arrest and apoptosis.
Subunit:
Homodimer; disulfide-linked. Dimer formation is driven by hydrophobic interactions within the N-terminal luminal domains and stabilized by disulfide bridges. Also binds HSPA5, a negative regulator of the unfolded protein response. This interaction may disrupt homodimerization and prevent activation of ERN1. Interacts with TAOK3 and TRAF2.
Subcellular Location:
Endoplasmic reticulum membrane.
Tissue Specificity:
Ubiquitously expressed. High levels observed in pancreatic tissue.
Post-translational modifications:
Autophosphorylated.
Similarity:
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
Contains 1 KEN domain.
Contains 1 protein kinase domain.
