cytosine in single-stranded DNA + H2O | Homo sapiens | activation-induced deaminase is the initiator for somatic hypermutation (SHM) and class switch recombination (CSR). The enzyme targets the highly repetitive switch regions of the immunoglobulin heavy chain locus to induce DNA double-strand breaks (DSBs), which can be rejoined, leading to switch of constant regions of antibody. When targeting to variable region exons of IgH and IgL loci, the enzyme predominantly induces point mutations, termed SHM, resulting in increased affinity of antibody for antigen. While somatic hypermutation and class switch recombination (CSR) enhance antibody diversity, activation-induced deaminase initiated double-strand breaks and mutations may predispose B cells to carcinogenesis | uracil in single-stranded DNA + NH3 | - |
