Somatic hypermutation and class-switch-recombination are initiated by the deamination of deoxycytosine in DNA by activation-induced-deaminase, AID. Recently, there has been much research into how AID targets double-stranded DNA in sub-regions of Ig genes, the involvement of co-factors and posttranslational modifications in this process, the co-option of DNA 'repair' mechanisms and AID evolution.
体细胞高频突变和类别转换重组是由激活诱导脱氨酶(AID)对DNA中的脱氧胞嘧啶进行脱氨作用引发的。最近,人们对AID如何靶向Ig基因亚区域中的双链DNA、该过程中辅助因子的参与情况和翻译后修饰、DNA“修复”机制的借用以及AID的进化进行了大量研究。
