Validation:
KO validation (Figure 2) : Anti-IRE1p antibody (3655) specificity was further verified by IRE1P specific knockout. IRE1p signal was disrupted in IRE1p knockout HeLa cells in comparison with that in control HeLa cells.
Induced Expression Validation (Figure 11) : IRE1p expression detected by anit-IRE1p antibodies was up-regulated by 20 (S) ‐PPD treatment.
Isoform: Human IRE1p has 2 isoforms, including isoform 1 (977aa, 110kD) and isoform 2 (70aa, 6.6kD) . Mouse IRE1p also has two isoforms, including isoform 1 (977aa, 110kD) and isoform 2 (408aa, 45kD) . Rat IRE1p has one isoform (965aa, 109kD) . 3655 can detect human, mouse and rat.
Purification: IRE1p Antibody is affinity chromatography purified via peptide column.

Alternate Name: IRE1p Antibody: IRE1, IRE1P, IRE1a, hIRE1p, IRE1, Endoplasmic reticulum-to-nucleus signaling 1
User Note: Optimal dilutions for each application to be determined by the researcher.
BACKGROUND: IRE1p Antibody: Accumulation of malfolded proteins in the endoplasmic reticulum (ER) activates the unfolded protein response (UPR) and the upregulation of the ER molecular chaperones GRP78 and GRP 94. These proteins are normally bound to ER transmembrane proteins such as IRE1p and ATF6 but ER stress causes their dissociation. This allows IRE1p, a serine-threonine protein kinase to transduce the unfolded protein signal from the ER to the nucleus. IRE1p also has an endoribonuclease activity that is required to splice X-box binding protein (XBP1) mRNA converting it to a potent UPR transcriptional activation. Depletion of IRE1p through the expression of a dominant negative form of IRE1p has no effect on transfected cells, but cell death via apoptosis occurs under stress conditions that cause unfolded proteins to accumulate in the ER. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene.
