. Nucleotide Weight Matrices Reveal Ubiquitous Mutational Footprints of AID/APOBEC Deaminases in Human Cancer Genomes. Cancers (Basel). 2019;11: pubmed publisher
..Overall, the weight matrix approach reveals that somatic mutations are significantly associated with at least one AID/APOBEC mutable motif in all studied cancers. ..
Stepchenkova E, Shiriaeva A, Pavlov Y. Deletion of the DEF1 gene does not confer UV-immutability but frequently leads to self-diploidization in yeast Saccharomyces cerevisiae. DNA Repair (Amst). 2018;70:49-54 pubmed publisher
..We conclude that Def1 does not play a critical role in damage-induced mutagenesis. ..

..In DNA polymerases δ and ζ, they can potentially play regulatory role by sensing hurdles during DNA replication and assisting with DNA polymerase switches by oscillation between oxidized-reduced states. ..

..Here we provide evidence that Pol ? is involved in the control of SAM in yeast cells starved for adenine by participation in sporadic replication and/or DNA repair under these conditions. ..
Mayorov V, Rogozin I, Adkison L, Frahm C, Kunkel T, Pavlov Y. Expression of human AID in yeast induces mutations in context similar to the context of somatic hypermutation at G-C pairs in immunoglobulin genes. BMC Immunol. 2005;6:10 pubmed
..This indicates that the intrinsic substrate specificity of AID itself is a primary determinant of mutational hotspots at G-C base pairs during SHM. ..

Pavlov Y, Maki S, Maki H, Kunkel T. Evidence for interplay among yeast replicative DNA polymerases alpha, delta and epsilon from studies of exonuclease and polymerase active site mutations. BMC Biol. 2004;2:11 pubmed
..This suggests that other polymerases can substitute for certain functions of polymerase epsilon. ..

..We have found that pol? activity strongly depends on the sequence of the template and that homopyrimidine runs create a strong barrier for DNA synthesis by pol?. ..
