Gene: Polg (DNA polymerase gamma, catalytic subunit) Rattus norvegicus
Symbol: Polg
Name: DNA polymerase gamma, catalytic subunit
RGD ID: 620057
Description: Enables DNA-directed DNA polymerase activity. Involved in several processes, including cellular response to glucose stimulus; response to gamma radiation; and response to hyperoxia. Located in terminal bouton. Part of gamma DNA polymerase complex. Used to study Alpers-Huttenlocher syndrome and hepatocellular carcinoma. Biomarker of status epilepticus. 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); INTERACTS WITH (+)-pilocarpine; 17beta-estradiol; 3,3',4,4',5-pentachlorobiphenyl.
Type: protein-coding
RefSeq Status: VALIDATED
Previously known as: 3'-5' exodeoxyribonuclease; 5'-deoxyribose-phosphate lyase; DNA polymerase gamma; DNA polymerase subunit gamma-1; DNA-directed DNA polymerase gamma; mitochondrial DNA polymerase catalytic subunit; polG-alpha; polymerase (DNA directed), gamma; polymerase (DNA) gamma, catalytic subunit
