特異性：This item recognises inositol-requiring kinase 1 precursor (IRE1p), a 108kDa serine-threonine kinase/endoribonuclease also known as ERN1. It is an endoplasmic reticulum (ER) transmembrane protein, normally bound to the ER molecular chaperones GRP78 and GRP94. At times of ER stress, due to accumulation of unfolded proteins, IRE1p becomes dissociated from the chaperones, which allows it to activate the un-folded protein transcriptional response (UPR). In the mammalian genome, there are two homologs Ire1alpha and Ire1beta. Ire1alpha is expressed in all cells and tissues, Ire1beta expression is primarily restricted to intestinal epithelial cells.
