Abasic sites are among the most abundant DNA lesions formed in human cells, and they present a strong block to replication. DNA polymerase iota (Poliota) is one of the few DNA Pols that does not follow the A-rule opposite an abasic site. We present here three structures of human Poliota in complex with DNAs containing an abasic lesion and dGTP, dTTP, or dATP as the incoming nucleotide ...
