Gene: POLG2 (DNA polymerase gamma 2, accessory subunit) Homo sapiens
Symbol: POLG2
Name: DNA polymerase gamma 2, accessory subunit
RGD ID: 1312978
Description: Exhibits DNA polymerase binding activity; DNA polymerase processivity factor activity; and double-stranded DNA binding activity. Involved in DNA-dependent DNA replication and positive regulation of DNA-directed DNA polymerase activity. Localizes to gamma DNA polymerase complex and mitochondrial nucleoid. Implicated in autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 4 and mitochondrial DNA depletion syndrome.
Type: protein-coding
RefSeq Status: REVIEWED
