Specific Aims
Activation-induced cytidine deaminase (AID) encodes a DNA-editing deaminase, which is a group of the Cytidine Deaminase family (Bello). This protein is concerned in somatic gene conversion, hypermutation, and class-switch recombination of Ig (immunoglobulin genes). Activation-induced cytidine deaminase (AID) has been expressed in B cells at germinal center and starts the events, which lead to class switch recombination of immunoglobulin genes and somatic hypermutation. Additionally to this primary responsibility in immune diversification, deviant targeting of Activation-induced cytidine deaminase activity leads to translocations and point mutations of oncogenes linked with B-cell lymphoma. Lately, AID has been related in active DNA demethylation (Sariah).
