CC -!- FUNCTION: Central component of a redox-sensitive mitochondrial
CC intermembrane space import machinery which is required for the
CC biogenesis of respiratory chain complexes (PubMed:26004228). Functions
CC as chaperone and catalyzes the formation of disulfide bonds in
CC substrate proteins, such as COX17, COX19, MICU1 and COA7
CC (PubMed:16185709, PubMed:26387864, PubMed:19182799, PubMed:21059946,
CC PubMed:23186364, PubMed:23676665, PubMed:30885959). Required for the
CC import and folding of small cysteine-containing proteins (small Tim) in
CC the mitochondrial intermembrane space (IMS). Required for the import of
CC COA7 in the IMS (PubMed:30885959). Precursor proteins to be imported
CC into the IMS are translocated in their reduced form into the
CC mitochondria. The oxidized form of CHCHD4/MIA40 forms a transient
CC intermolecular disulfide bridge with the reduced precursor protein,
CC resulting in oxidation of the precursor protein that now contains an
CC intramolecular disulfide bond and is able to undergo folding in the IMS
CC (PubMed:16185709, PubMed:19182799, PubMed:21059946, PubMed:23676665).
CC Reduced CHCHD4/MIA40 is then reoxidized by GFER/ERV1 via a disulfide
CC relay system (PubMed:23186364). Mediates formation of disulfide bond in
CC MICU1 in the IMS, promoting formation of the MICU1-MICU2 heterodimer
CC that regulates mitochondrial calcium uptake (PubMed:26387864).

CC -!- SUBUNIT: Monomer (PubMed:19182799). Can form homooligomers
CC (PubMed:16185709). Interacts with GFER and forms transient disulfide
CC bonds with GFER (PubMed:23186364, PubMed:23676665). Interacts with
CC MICU1 (PubMed:26387864). Interacts with COX19 forming transient
CC intermolecular disulfide bridges (PubMed:23676665). Interacts with COA7
CC through transient intermolecular disulfide bonds (PubMed:30885959).
CC Interacts with AIFM1; the interaction increases in presence of NADH
CC (PubMed:26004228). Interacts with NDUFB10; assists NDUFB10 oxidation,
CC folding and import into mitochondrion. {ECO:0000269|PubMed:16185709,
