Target Background

Function
Copper metallochaperone essential for the synthesis and maturation of cytochrome c oxidase subunit II (MT-CO2/COX2). Involved in transporting copper to the Cu(A) site on MT-CO2/COX2. Also acts as a thiol-disulfide oxidoreductase to regulate the redox state of the cysteines in SCO1 during maturation of MT-CO2/COX2.
Gene References into Functions
  1. We identified one novel possibility of an extreme myopia-causing mutation in SCO2. No other disease-causing mutation was found in 101 extremely myopic Japanese patients, suggesting that SCO2 plays a limited role in Japanese extreme myopia. PMID: 27052445
  2. In gastric cancer, the expression of SCO2 and COX were not shown to be associated with the regulatory role of p53, unlike TIGAR expression. Nevertheless, a significantly high recurrence rate was found in a patient group with high COX expression PMID: 27499152
  3. oxidative stress-induced glycolysis-to-OXPHOS switch is mediated by synthesis of cytochrome c oxidase 2 (SCO2). These findings demonstrate p53-mediated OXPHOS function as a compensatory alteration in Fanconi anemia (FA)hematopoietic stem cells to ensure a functional but mildly impaired energy metabolism and suggest a cautious approach to manipulating p53 signaling in FA. PMID: 26676373
  4. Geranylgeranoic acid increased the SCO2 gene expression, which might enhance aerobic respiration. PMID: 26700591
  5. oncoprotein HBXIP enhances glucose metabolism reprogramming through suppressing SCO2 and PDHA1 in breast cancer PMID: 26309161
  6. Cooperation between COA6 and SCO2 in COX2 maturation during cytochrome c oxidase assembly links two mitochondrial cardiomyopathies. PMID: 25959673
  7. 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. PMID: 26351686
  8. Letter/Case Report: SCO2 mutations resulting in Leigh disease revealed at autopsy. PMID: 25720770
  9. mutation in LRPAP1 is associated with high myopia. Further studies are expected to evaluate the pathogenicity of the variants in CTSH, LEPREL1, ZNF644, SLC39A5, and SCO2. PMID: 25525168
  10. COX20 cooperates with SCO1 and SCO2 to mature COX2 and promote the assembly of cytochrome c oxidase. PMID: 24403053
  11. alpha-particle-induced bystander effect is regulated by p53 and its downstream SCO2 in the irradiated hepatoma cells PMID: 23786650
  12. oroxylin A could increase protein and mRNA expression of TP53-induced glycolysis and apoptosis regulator (TIGAR) and synthesis of cytochrome c oxidase 2 (SCO2), which are the key metabolic modulators regulated by p53. PMID: 23612020
  13. Autosomal recessive mutations in SCO2 are known to be associated with COX deficiency recognized as fatal infantile cardio-encephalomyopathy PMID: 23364397

  15. Mutations in SCO2 are associated with autosomal-dominant high-grade myopia. PMID: 23643385
  16. Analysis of the mtDNA revealed that COX deficiency is caused by high levels of mtDNA deletions which accumulate with age in alzheimer disease. PMID: 21925769
  17. wild-type p53 gene silencing reduced the expression of synthesis of cytochrome c oxidase 2 (SCO2), an effector necessary for respiratory chain function PMID: 22120717

  19. Results describe the tissue distribution of SCO1 and SCO2 in mouse and human tissues. PMID: 20864674
  20. Mutations of SCO2 gene should be considered as a possible cause of neurogenic skeletal muscle features (including SMA-like) in infants with encephalomyopathy even in the absence of heart involvement and COX deficit. PMID: 19879173
  21. recombinant fusion L-Sco2 protein was successfully transduced into the mitochondria of primary fibroblasts derived from SCO2/COX deficient patient and facilitated recovery of COX activity PMID: 20193760

  28. data suggest that both Cu(I) and Cu(II) binding are critical for normal Sco function. PMID: 16091356

  30. These results suggest a mitochondrial pathway for the regulation of cellular copper content that involves signaling through SCO1 and SCO2, perhaps by their thiol redox or metal-binding state. PMID: 17189203
  31. structural and metal binding features of human Cu(I)Sco2 are similar to the Sco1 homolog, although the dynamic properties and the conformational disorder are quite different when apo forms and the copper(I)-loaded forms of the two proteins are compared PMID: 17850752
