| Mgi Type | protein coding gene |
| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Enables exonuclease activity. Acts upstream of or within determination of adult lifespan and mitochondrial DNA replication. Located in mitochondrial inner membrane. Is expressed in several structures, including 2-cell stage conceptus; 8-cell stage conceptus; blastocyst-stage conceptus; early embryo; and secondary oocyte. Used to study bipolar disorder; mood disorder; and 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. Orthologous to human POLG (DNA polymerase gamma, catalytic subunit). PHENOTYPE: Homozygous proof-reading deficient mutants display reduced life spans and premature aging with weight loss, decreased subcutaneous fat, alopecia, kyphosis, osteoporosis, anemia, reduced fertility, and enlarged hearts. Homozygous null mice display embryonic lethality. [provided by MGI curators] |
