This antibody reacts with overexpressed and endogenous POL beta protein. A BLAST analysis was used to suggest reactivity with POL beta from human, bovine, and Xenopus laevis based on a 100% homology with the immunizing sequence. Cross-reactivity with POL beta from other sources has not been determined.
DNA polymerase beta comprises an amino-terminal 8- kDa domain and a carboxy-terminal 31- kDa domain. The N-terminal ssDNA binding domain has a deoxyribose phosphodiesterase activity while the C-terminal domain has a nucleotidyltransferase activity. Mammalian DNA polymerase beta, a DNA repair polymerase, is constitutively expressed in cultured cells, but treatment of cells with the DNA-alkylating agents such as N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) or methyl methanesulfonate up-regulates beta-pol level. DNA polymerase beta fills single nucleotide gaps in DNA produced by the base excision repair pathway of mammalian cells.
