Previous GeneCards Identifiers for CHCHD4 Gene
CHCHD4, a component of human mitochondria, belongs to a protein family whose members share 6 highly conserved cysteine residues constituting a -CXC-CX(9)C-CX(9)C- motif in the C terminus (Hofmann et al., 2005 [PubMed 16185709]).[supplied by OMIM, Mar 2008]
GeneCards Summary for CHCHD4 Gene
CHCHD4 (Coiled-Coil-Helix-Coiled-Coil-Helix Domain Containing 4) is a Protein Coding gene. Among its related pathways are Mitochondrial protein import and Transport to the Golgi and subsequent modification. GO annotations related to this gene include protein disulfide oxidoreductase activity.
UniProtKB/Swiss-Prot for CHCHD4 Gene
Functions as chaperone and catalyzes the formation of disulfide bonds in substrate proteins, such as COX17. Required for the import and folding of small cysteine-containing proteins (small Tim) in the mitochondrial intermembrane space (IMS). Precursor proteins to be imported into the IMS are translocated in their reduced form into the mitochondria. The oxidized form of CHCHD4/MIA40 forms a transient intermolecular disulfide bridge with the reduced precursor protein, resulting in oxidation of the precursor protein that now contains an intramolecular disulfide bond and is able to undergo folding in the IMS. Reduced CHCHD4/MIA40 is then reoxidized by GFER/ERV1 via a disulfide relay system.
