Summary: 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). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
