WebIRE1 is an important central regulator of unfolded protein response (UPR) in the endoplasmic reticulum (ER) because of its ability to regulate cell fate as a function of stress sensing. When misfolded proteins accumulated in chondrocytes ER, IRE1 disintegrates with BIP/GRP78 and undergoes dimer/oligomerization and transautophosphorylation. WebInositol-requiring enzyme 1 (IRE1) is a bifunctional serine/threonine kinase and endoribonuclease that is a major mediator of the unfolded protein response (UPR) during …

WebNov 20, 2015 · CHOP induces the transcription of endoplasmic reticulum oxidoreductin 1 (ERO1α), which results in a hyperoxidizing environment in the ER. This may participate in cell death in vitro and in vivo, because knocking down ERO1α in Caenorhabditis elegans protects animals from tunicamycin [ 9]. WebMay 15, 2003 · IRE1 is an ER transmembrane glycoprotein and it contains both kinase and RNase activities in the cytoplasmic domain. ER stress leads to its autophosphorylation and the subsequent activation of its RNase activity. ... CHOP is a proapoptotic transcription factor that potentiates apoptosis.
