Allotopic Expression of Yeast COX2: A New Leap Forward for MitoSENS
To date, three of the thirteen OXPHOS genes still encoded in the mitochondria have been allotopically expressed (AE) in human cells with mutated versions of the same gene, thereby rescuing a respiratory defect. Now we have the first report of a new gene, COX2, being allotopically expressed in yeast, by mutating the gene to overcome the hydrophobicity of the mitochondrial membrane; a similar mutation has been shown to underlie the ability of the unusual case of the soybean COX2, which is a case of a native nuclear-encoded COX2 gene.
