Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables exonuclease activity. Involved in mitochondrial DNA replication. Acts upstream of or within determination of adult lifespan. Located in mitochondrial inner membrane. Is expressed in several structures, including early conceptus and secondary oocyte. Used to study myelodysplastic syndrome. Human ortholog(s) of this gene implicated in several diseases, including mitochondrial DNA depletion syndrome (multiple); mitochondrial myopathy (multiple); neurodegenerative disease (multiple); ovarian disease (multiple); and sensory ataxic neuropathy, dysarthria, and ophthalmoparesis.
