英文摘要
Activation-induced cytidine deaminase (AID) is essential for class switch recombination of immunoglobulin genes. AID is required to introduce DNA lesions into switch region of immunoglobulin genes. However, an important question remains concerning how AID leads to double-strand DNA cleavage in switch region. Based on the hypothesis that a protein coded by the mRNA edited by AID generates DNA cleavage, I performed a rescue experiment for class switch recombination in AID-deficient B cells using retroviral cDNA library. Several candidate genes are now analyzed to confirm its role in class switch recombination.
