CC   -!- FUNCTION: Regulator of autophagy that contributes to antagonize becn1-
CC       mediated cellular autophagy at the endoplasmic reticulum. Participates
CC       in the interaction of bcl2 with becn1 and is required for bcl2-mediated
CC       depression of endoplasmic reticulum Ca(2+) stores during autophagy (By
CC       similarity). {ECO:0000250}.
CC   -!- COFACTOR:
CC       Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135; Evidence={ECO:0000250};
CC       Note=Binds 1 [2Fe-2S] cluster. {ECO:0000250};
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC       Single-pass membrane protein {ECO:0000250}. Mitochondrion outer
CC       membrane {ECO:0000250}; Single-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CISD protein family. CISD2 subfamily.
CC       {ECO:0000305}.
