Previous GeneCards Identifiers for ERN1 Gene
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.

GeneCards Summary for ERN1 Gene
ERN1 (Endoplasmic Reticulum To Nucleus Signaling 1) is a Protein Coding gene. Among its related pathways are Transport to the Golgi and subsequent modification and Translational Control. GO annotations related to this gene include protein homodimerization activity and transferase activity, transferring phosphorus-containing groups. An important paralog of this gene is ERN2.
UniProtKB/Swiss-Prot for ERN1 Gene
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.
IRE1 is a transmembrane resident ER protein that possesses both kinase and endonuclease domains. Both yeast (IRE) and mammalian (IRE1alpha) homologs are involved in the degradation of misfolded proteins, as part of the unfolded protein response (UPR) pathway.
