Biological function summary

AICDA plays an important role in the adaptive immune system by facilitating the diversification of antibodies. It does not appear to function as part of a larger protein complex but operates independently to induce mutations in variable regions of immunoglobulin genes. This activity enables B cells to produce antibodies with higher affinity and different isotypes important for an effective immune defense system. AICDA’s function ensures the generation of diverse antibody repertoires allowing the immune system to effectively target a wide range of pathogens.

Pathways

AICDA is integral to the immunoglobulin gene diversification pathway. It initiates somatic hypermutation and class switch recombination by deaminating cytosine residues in the DNA of immunoglobulin genes. This action relates AICDA to other proteins involved in DNA repair and error-prone replication such as uracil-DNA glycosylase (UNG) and the mismatch repair proteins like MSH2 and MSH6. AICDA's deamination activity triggers the recruitment of these proteins to introduce mutations and remove uracil residues facilitating the generation of antibody diversity.
