The IRE1 alpha ELISA kits listed below are analytical tools for measuring concentrations of IRE1 alpha in various samples. IRE1 alpha is an alternative name for the human ERN1 gene, which encodes the protein, endoplasmic reticulum to nucleus signaling 1. It has been mentioned that IRE1 alpha plays a role in carbohydrate metabolism and homeostasis and the apoptotic pathway, among other functions. Structurally, the ERN1 protein is 977 amino acid residues in length and 109.7 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the ER of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be phosphorylated and glycosylated. Other names for this target antigen include IRE1, IRE1, and IRE1P. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
