Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) 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; secondary oocyte; and telencephalon. 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] |
