- 说明书：
Description: Serine/threonine-protein kinase and endoribonuclease that acts as a key sensor for the endoplasmic reticulum unfolded protein response (UPR) (PubMed:11779464, PubMed:11175748, PubMed:12637535, PubMed:9637683, PubMed:21317875). 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 protein 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).
Post Translational Modifications: Autophosphorylated following homodimerization. Autophosphorylation promotes activation of the endoribonuclease domain. ADP-ribosylated by PARP16 upon ER stress, which increases both kinase and endonuclease activities.
Subunit Structure: Monomer (PubMed:29198525, PubMed:16973740). Homodimer; disulfide-linked; homodimerization takes place in response to endoplasmic reticulum stress and promotes activation of the kinase and endoribonuclease activities (PubMed:12637535, PubMed:24508390, PubMed:16973740, PubMed:21317875). Dimer formation is driven by hydrophobic interactions within the N-terminal luminal domains and stabilized by disulfide bridges (PubMed:12637535). Interacts (via the luminal region) with DNAJB9/ERdj4; interaction takes place in unstressed cells and promotes recruitment of HSPA5/BiP (PubMed:29198525). Interacts (via the luminal region) with HSPA5/BiP; HSPA5/BiP is a negative regulator of the unfolded protein response (UPR) that prevents homodimerization of ERN1/IRE1 and subsequent activation of the protein (PubMed:12637535, PubMed:29198525). Interacts with PDIA6, a negative regulator of the UPR; the interaction is direct and disrupts homodimerization (PubMed:24508390). Interacts with DAB2IP (via PH domain); the interaction occurs in a endoplasmic reticulum stress-induced dependent manner and is required for subsequent recruitment of TRAF2 to ERN1/IRE1 (By similarity). Interacts with TAOK3 and TRAF2 (PubMed:11278723).
Similarity: Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
