General description
A cell-permeable thiol reactive enone (EN) compound that selectively interacts with the active-site cysteine of reduced, active form of ERO1α and inhibits its activity (IC50 = 1.9 µM). Also prevents ERO1 re-oxidation both in vitro and in mouse embryonic fibroblasts. Activates the unfolded protein response and protects ER-stressed 293T cells. Can inhibit ERO1α even in the presence of an excess amount of competing thiols. Can inhibit ERO1α even in the presence of an excess amount of competing thiols. EN460 binding to ERO1α is shown to promote the loss of flavin adenine dinucleotide (FAD) from the holoenzyme. Its inhibitory action appears to be irreversible, however addition of FAD and tris(hydroxypropyl)phosphine (Cat. No. 598250) can restore some enzyme activity.

The flavin adenine dinucleotide containing Endoplasmic Reticulum Oxidoreductase-1 α (ERO1α) catalyzes the formation of de novo disulfide bond formation of secretory and transmembrane proteins and contributes towards proper protein folding. Recently, increased ERO1α expression has been shown to contribute to

Endoplasmic reticulum (ER) homeostasis requires molecular regulators that tailor mitochondrial bioenergetics to the needs of protein folding. For instance, calnexin maintains mitochondria metabolism and mitochondria-ER contacts (MERCs) through reactive oxygen species (ROS) from NADPH oxidase 4 (NOX4). However, induction of
