Disease

ALR_HUMAN Congenital cataract - progressive muscular hypotonia - hearing loss - developmental delay. The disease is caused by mutations affecting the gene represented in this entry.

Function

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.[1] [2] [3] [4] [5] Isoform 2: May act as an autocrine hepatotrophic growth factor promoting liver regeneration.[6] [7] [8] [9] [10]
