CC -!- FUNCTION: Oxidoreductase involved in disulfide bond formation in the
CC endoplasmic reticulum. Efficiently reoxidizes P4HB/PDI, the enzyme
CC catalyzing protein disulfide formation, in order to allow P4HB to
CC sustain additional rounds of disulfide formation. Following P4HB
CC reoxidation, passes its electrons to molecular oxygen via FAD, leading
CC to the production of reactive oxygen species (ROS) in the cell.
CC Required for the proper folding of immunoglobulins. Plays an important
CC role in ER stress-induced, CHOP-dependent apoptosis by activating the
CC inositol 1,4,5-trisphosphate receptor IP3R1.
CC {ECO:0000250|UniProtKB:Q96HE7}.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000250|UniProtKB:Q96HE7};
CC -!- ACTIVITY REGULATION: Enzyme activity is tightly regulated to prevent
CC the accumulation of reactive oxygen species in the endoplasmic
CC reticulum. Reversibly down-regulated by the formation of disulfide
CC bonds between the active site Cys-94 and Cys-131, and between Cys-99
CC and Cys-104. Glutathione may be required to regulate its activity in
CC the endoplasmic reticulum (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Predominantly monomer. May function both as a monomer and a
CC homodimer. Interacts with PDILT. Interacts with ERP44; the interaction
CC results in retention of ERO1A in the endoplasmic reticulum.
CC {ECO:0000250|UniProtKB:Q96HE7}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q96HE7}; Peripheral membrane protein
CC {ECO:0000250|UniProtKB:Q96HE7}; Lumenal side
CC {ECO:0000250|UniProtKB:Q96HE7}. Golgi apparatus lumen
CC {ECO:0000250|UniProtKB:Q96HE7}. Secreted
CC {ECO:0000250|UniProtKB:Q96HE7}. Cell projection, dendrite
CC {ECO:0000250|UniProtKB:Q8R4A1}. Note=The association with ERP44 is
CC essential for its retention in the endoplasmic reticulum (By
CC similarity). In neurons, it localizes to dendrites (By similarity).
CC {ECO:0000250|UniProtKB:Q8R4A1, ECO:0000250|UniProtKB:Q96HE7}.
CC -!- PTM: The Cys-94/Cys-99 and Cys-394/Cys-397 disulfide bonds constitute
CC the redox-active center. The Cys-94/Cys-99 disulfide bond may accept
CC electron from P4HB and funnel them to the active site disulfide Cys-
CC 394/Cys-397. The regulatory Cys-99/Cys-104 disulfide bond stabilizes
CC the other regulatory bond Cys-94/Cys-131 (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Phosphorylated on Ser-145 by FAM20C in the Golgi which increases
CC its enzymatic activity (By similarity). Phosphorylation is induced by
CC lactation (By similarity). It is also induced by hypoxia and reductive
CC stress (By similarity). {ECO:0000250|UniProtKB:Q8R180,
CC ECO:0000250|UniProtKB:Q96HE7}.
CC -!- SIMILARITY: Belongs to the EROs family. {ECO:0000305}.
