title: Immunoglobulin genes: generating diversity with AID and UNG.
abstract: Somatic hypermutation and switch recombination of immunoglobulin genes require the activity of the activation-induced deaminase, AID. Recent studies of mice deficient for the uracil-DNA glycosylase UNG, which removes U from DNA, suggest that AID catalyses the deamination of dC to dU during antibody diversification.
