DNA polymerase eta is the sole contributor of A/T modifications during immunoglobulin gene hypermutation in the mouse

Mutations at A/T bases within immunoglobulin genes have been shown to be generated by a repair pathway involving the DNA-binding moiety of the mismatch repair complex constituted by the MSH2-MSH6 proteins, together with DNA polymerase eta (pol eta). However, residual A/T mutagenesis is still observe...
