Summary: Mammalian cytochrome c oxidase (COX) catalyzes the transfer of reducing equivalents from cytochrome c to molecular oxygen and pumps protons across the inner mitochondrial membrane. In yeast, 2 related COX assembly genes, SCO1 and SCO2 (synthesis of cytochrome c oxidase), enable subunits 1 and 2 to be incorporated into the holoprotein. This gene is the human homolog to the yeast SCO1 gene. [provided by RefSeq, Jul 2008]

Results find that COA6 associates with COX2 and is crucial for its maturation and complex IV biogenesis. Also, COA6 interacts with the copper chaperone SCO1 which indicates that COA6 is intrinsically involved in the copper delivery process for COX2.
Title: COA6 is a mitochondrial complex IV assembly factor critical for biogenesis of mtDNA-encoded COX2.
Sco1 is a metallochaperone that selectively transfers Cu(I) ions based on loop recognition, whereas Sco2 is a copper-dependent thiol reductase of the cysteine ligands in the oxidase.
Title: Loop recognition and copper-mediated disulfide reduction underpin metal site assembly of CuA in human cytochrome oxidase.
COX20 cooperates with SCO1 and SCO2 to mature COX2 and promote the assembly of cytochrome c oxidase.
Title: Human COX20 cooperates with SCO1 and SCO2 to mature COX2 and promote the assembly of cytochrome c oxidase.
COX19 is necessary for the transduction of a SCO1-dependent mitochondrial redox signal that regulates ATP7A-mediated cellular copper efflux.
Title: COX19 mediates the transduction of a mitochondrial redox signal from SCO1 that regulates ATP7A-mediated cellular copper efflux.
Results describe the tissue distribution of SCO1 and SCO2 in mouse and human tissues.

a fraction of Sco1 physically associates with the cytochrome c oxidase complex in human muscle mitochondria, suggesting a possible direct relationship between CcO and the regulation of cellular copper homeostasis
Title: Loss of function of Sco1 and its interaction with cytochrome c oxidase.
Cu(I)HCox17(2S-S), i.e., the copper-loaded form of the protein, can transfer simultaneously copper(I) and two electrons to the human cochaperone Sco1 (HSco1) in the oxidized state, i.e., with its metal-binding cysteines forming a disulfide bond.
Title: Mitochondrial copper(I) transfer from Cox17 to Sco1 is coupled to electron transfer.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
