Cat.No. : POLK-137H
Product Overview : This product was over-expressed as a recombinant protein in E. coli with a plasmid carrying a C-terminal histidine-tagged human DNA polymerase κ (1-560 aa), and highly purified by several steps of chromatography. The product is catalytically active and its molecular weight is 65 kD. Activity of this product has been confirmed by a user researcher even if it was diluted 8,000-fold.
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.
