Activation-induced cytidine deaminase-dependent DNA breaks in class switch recombination occur during G₁ phase of the cell cycle and depend upon mismatch repair.

Schrader, C. E., J. E. J. Guikema, E. K. Linehan, E. Selsing, and J. Stavnezer. 2007. Activation-induced cytidine deaminase-dependent DNA breaks in class switch recombination occur during G₁ phase of the cell cycle and depend upon mismatch repair. J. Immunol. 179: 6064–6071 .

In the Introduction, in the last sentence of the first paragraph on page 6064, the word “deaminated” was misspelled. The sentence should read: “The underlined C is deaminated by AID.”
