Three phenotypically distinct processes--somatic
hypermutation, gene conversion, and switch recombination--remodel the
functionallyrearranged immunoglobulin (Ig) loci in B cells. Somatic
hypermutationand switch recombination have recently been shown to
depend onthe activation-induced deaminase (AID) gene
product. Here, weshow that the disruption of the AID gene
in the chicken B cellline DT40 completely blocks Ig gene conversion
and that this blockcan be complemented by reintroduction of the
AID complementaryDNA. This demonstrates that the
AID master gene controls all Bcell-specific
modifications of vertebrate Ig genes.
