Description
Mammalian DNA polymerase κ, a member of the UmuC/DinB nucleotidyl transferase superfamily, has been implicated in spontaneous mutagenesis. Human DNA polymerase κ copies undamaged DNA with average single-base subsitution and deletion error rates of 7 x 10^-3 and 2 x 10^-3, respectively. These error rates are high when compared to those of most other DNA polymerases. DNA polymerase κ has important role in the mutagenic bypass of certain types of DNA lesions
