Involvement of DNA polymerase beta overeion in the Jul 05, 2013 · This mutant pol along with the others, i.e. pol E295K, K289M and I260M mutants identified in gastric cancer, colon cancer and prostate cancer can compete with wild-type pol to interfere base lesion repair conferring a dominant-negative effect on BER leading to cellular malignant transformation phenotypes such as loss of anchorage Leu22Pro tumor-associated variant of DNA polymerase beta Nov 26, 2007 · The gastric cancer-associated E295K variant is polymerase deficient and acts in a dominant negative manner to interfere with BER. This variant also induces sister chromatid exchanges in mouse cells ( 16 ).

Unfavorable Electrostatic and Steric Interactions in DNA

Mutations in DNA polymerase (pol ) have been associated with approximately 30% of human tumors. The E295K mutation of pol has been linked to gastric carcinoma via interference with base excision repair. To interpret the different behavior of E295K as compared to wild-type pol in atomic and energetic detail, we resolve a binary crystal complex of E295K at 2.5 Å and apply transition Unfavorable electrostatic and steric interactions in DNA Mutations in DNA polymerase (pol ) have been associated with approximately 30% of human tumors.
