MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the processivity subunit of the mitochondrial DNA polymerase gamma. The encoded protein forms a heterotrimer containing one catalytic subunit and two processivity subunits. This protein enhances DNA binding and promotes processive DNA synthesis. Mutations in this gene result in autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions.[provided by RefSeq, Sep 2009]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit embryonic lethality between somite formation and turning, fail to initiate turning, lack mt-Co1 activity, and contain abnormal mitochondria with reduced mtDNA. [provided by MGI curators]
