Co-option of retrotransposons promotes antibody diversification.

Activation-induced cytidine deaminase (AID) accomplishes somatic hypermutation (SHM) of V H (D)J H genes in germinal center B cells for antibody diversification and affinity maturation.

Activation-induced cytidine deaminase (AID) accomplishes somatic hypermutation (SHM) of V H (D)J H genes in germinal center B cells for antibody diversification and affinity maturation. How AID specifically targets V H (D)J H remains unclear. We report the discovery of LINE-1…
