Polymerase (DNA directed) nu is a protein in humans that is encoded by the POLN gene.[1] It is a family ADNA polymerase,[2] considered to be the least effective of the polymerase enzymes.[3] However, DNA polymerase nu plays an active role in homology repair during cellular responses to crosslinks, fulfilling its role in a complex with helicase.[3]
