What is "primpol"

PrimPol is a protein encoded by the PRIMPOL gene in humans. PrimPol is a eukaryotic protein with both DNA polymerase and DNA Primase activities involved in translesion DNA synthesis. It is the first eukaryotic protein to be identified with priming activity using deoxyribonucleotides. It is also the first protein identified in the mitochondria to have translesion DNA synthesis activities.
