In unstressed cells, the endoplasmic reticulum luminal domain is maintained in its inactive monomeric state by binding to the endoplasmic reticulum chaperone HSPA5\/BiP (PubMed:21317875). Accumulation of misfolded proteins in the endoplasmic reticulum causes release of HSPA5\/BiP, allowing the luminal domain to homodimerize, promoting autophosphorylation of the kinase domain and subsequent activation of the endoribonuclease activity (PubMed:21317875). The endoribonuclease activity is specific for XBP1 mRNA and excises 26 nucleotides from XBP1 mRNA (PubMed:11779464, PubMed:24508390, PubMed:21317875). The resulting spliced transcript of XBP1 encodes a transcriptional activator protein that up-regulates expression of UPR target genes (PubMed:11779464, PubMed:24508390, PubMed:21317875). Acts as an upstream signal for ER stress-induced GORASP2-mediated unconventional (ER\/Golgi-independent) trafficking of CFTR to cell membrane by modulating the expression and localization of SEC16A (PubMed:21884936, PubMed:28067262). {ECO:0000269|PubMed:11175748, ECO:0000269|PubMed:11779464, ECO:0000269|PubMed:12637535, ECO:0000269|PubMed:21317875, ECO:0000269|PubMed:21884936, ECO:0000269|PubMed:28067262, ECO:0000269|PubMed:28128204, ECO:0000269|PubMed:9637683, ECO:0000305|PubMed:24508390}.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e:ELISA\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTarget_protein\u003c\/b\u003e:ERN1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReactivity\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay type\u003c\/b\u003e:Sandwich\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSensitivity\u003c\/b\u003e:0.27ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDetection range\u003c\/b\u003e:0.5-32ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSample type\u003c\/b\u003e:Serum, plasma or other biological fluids\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Endoplasmic Reticulum To Nucleus Signalling 1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecies\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e:2-8ºC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay time\u003c\/b\u003e:1h 30m\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUniProt accession\u003c\/b\u003e:O75460\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMASS(Da)\u003c\/b\u003e:109735\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGeneID\u003c\/b\u003e:2081\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSynonyms\u003c\/b\u003e:ERN1 IRE1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGene names\u003c\/b\u003e:ERN1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStandard solution\u003c\/b\u003e:64ng\/ml\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48648110538852,"sku":"E4839Hu","price":847.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_f13f309f-c1fb-49ff-bcb7-83ce1614334d.jpg?v=1782709018","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/human-endoplasmic-reticulum-to-nucleus-signalling-1-ern1-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
