[https://www.uniprot.org/uniprot/ALR_HUMAN ALR_HUMAN] Isoform 1: FAD-dependent sulfhydryl oxidase that regenerates the redox-active disulfide bonds in CHCHD4/MIA40, a chaperone essential for disulfide bond formation and protein folding in the mitochondrial intermembrane space. The reduced form of CHCHD4/MIA40 forms a transient intermolecular disulfide bridge with GFER/ERV1, resulting in regeneration of the essential disulfide bonds in CHCHD4/MIA40, while GFER/ERV1 becomes re-oxidized by donating electrons to cytochrome c or molecular oxygen.<ref>PMID:19397338</ref> <ref>PMID:23186364</ref> <ref>PMID:20593814</ref> <ref>PMID:21383138</ref> <ref>PMID:22224850</ref> Isoform 2: May act as an autocrine hepatotrophic growth factor promoting liver regeneration.<ref>PMID:19397338</ref> <ref>PMID:23186364</ref> <ref>PMID:20593814</ref> <ref>PMID:21383138</ref> <ref>PMID:22224850</ref>

== Publication Abstract from PubMed ==
 +
The oxidative folding mechanism in the intermembrane space of human mitochondria underpins a disulfide relay system consisting of the import receptor Mia40 and the homodimeric FAD-dependent thiol oxidase ALR. The flavoprotein ALR receives two electrons per subunit from Mia40, which are then donated through one-electron reactions to two cytochrome c molecules, thus mediating a switch from two-electron to one-electron transfer. We dissect here the mechanism of the electron flux within ALR, characterizing at the atomic level the ALR intermediates that allow electrons to rapidly flow to cytochrome c. The intermediate critical for the electron-transfer process implies the formation of a specific inter-subunit disulfide which exclusively allows electron flow from Mia40 to FAD. This finding allows us to present a complete model for the electron-transfer pathway in ALR.
