RT complex assembly and supercomplex stabilization.";
RL Mol. Cell. Biol. 35:1139-1156(2015).
CC -!- FUNCTION: Required for the assembly of the ubiquinol-cytochrome c
CC reductase complex (mitochondrial respiratory chain complex III or
CC cytochrome b-c1 complex), mediating cytochrome b recruitment and
CC probably stabilization within the complex. Thereby, plays an
CC important role in ATP production by mitochondria. Cardiolipin-
CC binding protein, it may also control the cardiolipin composition
CC of mitochondria membranes and their morphology.
CC {ECO:0000269|PubMed:25008109, ECO:0000269|PubMed:25605331}.
CC -!- SUBUNIT: Associates with the ubiquinol-cytochrome c reductase
CC complex (mitochondrial respiratory chain complex III or cytochrome
CC b-c1 complex). {ECO:0000269|PubMed:25605331}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:25008109, ECO:0000269|PubMed:25605331};
CC Single-pass membrane protein {ECO:0000269|PubMed:25008109,
CC ECO:0000269|PubMed:25605331}.
CC -!- PTM: Probably cleaved by OMA1 under mitochondrial stress
CC conditions. {ECO:0000269|PubMed:25605331}.
CC -!- DISEASE: Mitochondrial complex III deficiency, nuclear 9 (MC3DN9)
CC [MIM:616111]: A form of mitochondrial complex III deficiency, a
CC disorder of the mitochondrial respiratory chain resulting in a
CC highly variable phenotype depending on which tissues are affected.
CC MC3DN9 clinical features include feeding difficulties,
CC hypoglycemia, severe lactic acidosis, and delayed psychomotor
CC development. {ECO:0000269|PubMed:25008109}. Note=The disease is
CC caused by mutations affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the UQCC3 family. {ECO:0000305}.
CC -!- CAUTION: Was initially reported to be secreted (PubMed:15340161).
CC However, it was later shown to be localized in the inner
CC mitochondrial membrane (PubMed:25008109, PubMed:25605331).
