POLG2
| View/Edit Human | View/Edit Mouse |
DNA polymerase subunit gamma-2, mitochondrial is an protein that in humans is encoded by the POLG2 gene. The POLG2 gene encodes a 55 kDa accessory subunit protein that imparts high processivity and salt tolerance to the catalytic subunit of DNA polymerase gamma, encoded by the POLG gene.[3][4][5]
