DESCRIPTION

Also known as ERO1A_HUMAN, ERO1A, ERO1L. Oxidoreductase involved in disulfide bond formation in the endoplasmic reticulum. Efficiently reoxidizes P4HB/PDI, the enzyme catalyzing protein disulfide formation, in order to allow P4HB to sustain additional rounds of disulfide formation. Following P4HB reoxidation, passes its electrons to molecular oxygen via FAD, leading to the production of reactive oxygen species (ROS) in the cell. Required for the proper folding of immunoglobulins (PubMed:29858230). Plays an important role in ER stress-induced, CHOP-dependent apoptosis by activating the inositol 1, 4, 5-trisphosphate receptor IP3R1. Involved in the release of the unfolded cholera toxin from reduced P4HB/PDI in case of infection by V.cholerae, thereby playing a role in retrotranslocation of the toxin. Predominantly monomer. May function both as a monomer and a homodimer. Interacts with PDILT (PubMed:15475357). Interacts with ERP44; the interaction results in retention of ERO1A in the endoplasmic reticulum (PubMed:29858230, PubMed:11847130).
