Predicted to enable FAD binding activity; protein-disulfide reductase activity; and thiol oxidase activity. Predicted to be involved in protein folding in endoplasmic reticulum and ubiquitin-dependent protein catabolic process. Predicted to be located in endoplasmic reticulum. Predicted to be part of proteasome core complex, alpha-subunit complex. Is an ortholog of C. elegans
ero-1. In C. elegans,
ero-1 is involved in IRE1-mediated unfolded protein response and protein folding in endoplasmic reticulum.
