DNA Polymerase γ, The Mitochondrial Replicase
Abstract
DNA polymerase (pol) gamma is the sole DNA polymerase in animal mitochondria. Biochemical and genetic evidence document a key role for pol gamma in mitochondrial DNA replication, and whereas DNA repair and recombination were thought to be limited or absent in animal mitochondria, both have been demonstrated in recent years. Thus, the mitochondrial replicase is also apparently responsible for the relevant DNA synthetic reactions in these processes. Pol gamma comprises a catalytic core in a heterodimeric complex with an accessory subunit. The two-subunit holoenzyme is an efficient and processive polymerase, which exhibits high fidelity in nucleotide selection and incorporation while proofreading errors with its intrinsic 3' 5' exonuclease. Incorporation of nucleotide analogs followed by proofreading failure leads to mitochondrial toxicity in antiviral therapy, and misincorporation during DNA replication leads to mitochondrial mutagenesis and dysfunction. This review describes our current understanding of pol gamma biochemistry and biology, and it introduces other key proteins that function at the mitochondrial DNA replication fork.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
