    ..Overall, the weight matrix approach reveals that somatic mutations are significantly associated with at least one AID/APOBEC mutable motif in all studied cancers. ..

    ..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. ..

    ..This indicates that the intrinsic substrate specificity of AID itself is a primary determinant of mutational hotspots at G-C base pairs during SHM. ..

    ..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?. ..
