Protein SCO2 homolog, mitochondrial
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 (PubMed:15229189, PubMed:17189203). Also acts as a thiol-disulfide oxidoreductase to regulate the redox state of the cysteines in SCO1 during maturation of MT-CO2/COX2 (PubMed:19336478).
Involvement in disease
Mitochondrial complex IV deficiency, nuclear type 2
MC4DN2
An autosomal recessive, severe mitochondrial disorder characterized by hypotonia, global developmental delay, hypertrophic cardiomyopathy, lactic acidosis, gliosis, and neuronal loss in basal ganglia, brainstem and spinal cord. Serum lactate is increased, and laboratory studies show decreased mitochondrial complex IV protein and activity levels in various tissues, including heart and skeletal muscle. Most patients die in infancy of cardiorespiratory failure.
None
The disease is caused by variants affecting the gene represented in this entry.
Myopia 6
MYP6
A refractive error of the eye, in which parallel rays from a distant object come to focus in front of the retina, vision being better for near objects than for far.
None
The disease is caused by variants affecting the gene represented in this entry.
Sequence Similarities
Belongs to the SCO1/2 family.
Tissue Specificity
Ubiquitous.
