Summary: Enables copper ion binding activity. Involved in cell redox homeostasis; cellular response to oxidative stress; and mitochondrial cytochrome c oxidase assembly. Located in mitochondrial inner membrane. Used to study hypertrophic cardiomyopathy and liver disease. Human ortholog(s) of this gene implicated in cytochrome-c oxidase deficiency disease; hypertrophic cardiomyopathy; mitochondrial complex IV deficiency nuclear type 2; mitochondrial complex IV deficiency nuclear type 4; and myopia. Orthologous to several human genes including SCO1 (synthesis of cytochrome C oxidase 1). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Rho0 cells demonstrated loss of Sco1, resulting in copper deficiency by lowering copper transporter 1 abundance, via mechanism involving increased turnover due to ubiquitination. These findings reveal that a Sco1-dependent mitochondrial signal regulates cellular cisplatin import and cytotoxicity.
Title: Low Ctr1p, due to lack of Sco1p results in lowered cisplatin uptake and mediates insensitivity of rho0 yeast to cisplatin.
HCC1 of Arabidopsis is the homologue of the Saccharomyces cerevisiae SCO1.
Title: HCC1, the Arabidopsis homologue of the yeast mitochondrial copper chaperone SCO1, is essential for embryonic development.
Thiese data suggest that the absence of Sco1p causes irreversible damage to the mitochondria.
Title: Novel insights into phenotype and mitochondrial proteome of yeast mutants lacking proteins Sco1p or Sco2p.
These studies implicate different surfaces on Sco1 for interaction or function with Cox17 and Cox2.
Title: Mapping the functional interaction of Sco1 and Cox2 in cytochrome oxidase biogenesis.
Data show that hydrogen peroxide sensitivity of sco1Delta and cox11Delta cells is abrogated by overexpression of a novel mitochondrial ATPase Afg1 that promotes the degradation of CcO mitochondrially encoded subunits.
Title: Evidence for a pro-oxidant intermediate in the assembly of cytochrome oxidase.
THe copper binding site is co-translationally formed by a transient interaction between Cox11p and this nascent cytochrome C oxidase in the intermembrane space.
Title: Evidence for the association of yeast mitochondrial ribosomes with Cox11p, a protein required for the Cu(B) site formation of cytochrome c oxidase.
Sco1 exhibits a thioredoxin-like fold, similar to that observed for human Sco1.
Title: Crystal structure of yeast Sco1.

Preferred Names: Cu-binding protein SCO1

NP_009593.1

Copper-binding protein of mitochondrial inner membrane; required for cytochrome c oxidase activity and respiration; may function to deliver copper to cytochrome c oxidase; similar to thioredoxins; SCO1 has a paralog, SCO2, that arose from the whole genome duplication
