Protein Structure

UniProt Annotation

Function

Metalloreductase that has the ability to reduce both Fe(3+) to Fe(2+) and Cu(2+) to Cu(1+). Uses NAD(+) as acceptor (By similarity). {ECO:0000250}.

Subcellular Localization

Endosome membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Cell membrane {ECO:0000269PubMed:12429817}; Multi-pass membrane protein {ECO:0000269PubMed:12429817}.

Disease Associations

Tissue Specificity

Expressed at high levels in prostate and at significantly lower levels in heart, brain, kidney, pancreas, and ovary. {ECO:0000269PubMed:12095985, ECO:0000269PubMed:12429817, ECO:0000269PubMed:16609065}.
