This entry represents Activation-induced cytidine deaminase (AID), which is a single-stranded DNA-specific cytidine deaminase. It is involved in somatic hypermutation, gene conversion, and class-switch recombination in B-lymphocytes by deaminating C to U during transcription of Ig-variable and Ig-switch region DNA. It is required for several crucial steps of B-cell terminal differentiation necessary for efficient antibody responses [4].	Domain
