Abstract excerpt
Despite the remarkable fidelity of eukaryotic DNA replication, nucleotide misincorporation errors occur in every replication cycle, generating mutations that drive genetic diseases and genome evolution. Here, we show that transcription factor (TF) proteins, key players in gene regulation, can increase mutagenesis from replication errors by directly competing with the recognition of DNA mismatches by MutSα, the...
