Description

Recombinant Protein

For maximum recovery please spin prior to use. Unless noted below, aliquots of the 5 μg, 10 μg and 20 μg sizes of kinase are not recommended as materials can be used in original packaging until exhausted. For larger sizes, the number of freeze/thaws may be reduced by preparing aliquots, aliquots below 20 μL are not recommended. Please never store a kinase diluted. If properly stored at -80C, this product is guaranteed for 6 months from date of purchase. This ERN1 recombinant human protein (468-end) was expressed in insect cells. ERN1 recombinant human protein is also available in our SelectScreen™ Kinase Profiling Service. Validated for use with the LanthaScreen™ Eu Kinase Binding assay Available in multiple pack sizes for convenient use Also available in our SelectScreen Kinase Profiling Service Protein Form: Recombinant, Active, Catalytic The gene accession number for ERN1 is NP_001424.3.

ERN1 serine/threonine kinase or endoplasmic reticulum to nucleus signaling 1 is the ER to nucleus signaling 1 protein, a human homologue of the yeast Ire1 gene product which possesses intrinsic kinase activity and an endoribonuclease activity and it is important in endoplasmic reticulum-based stress signals. ERN1 controls IRE1 proteolysis in mammalian cells. ERN1 has a critical function in extraembryonic cells that is essential for fetal viability. Specifically, IRE1 acts as the sensor of unfolded proteins in the ER that initiates transmittance of the unfolded protein signal from the ER to the nucleus by splicing XBP1 mRNA converting it into a potent unfolded-protein response transcriptional activator. Null mutants are viable, but IRE1 is essential for viability under stress conditions that cause unfolded proteins to accumulate in the ER. 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.
