Ku80基因的缺陷表达被认为是xrs-6中国仓鼠卵巢细胞系中V(D)J重组和DNA双链断裂修复缺陷的基础。我们现在表明,Ku80 基因中的突变涉及外显子 2 上游 15 bp 处的 G 到 A 转换。这种突变创建了一个新的剪接受体位点,导致生成 Ku80 转录本,由于 13 个核苷酸插入和由此产生的移码,该转录本无法编码功能性产物。
Defective expression of theKu80gene has been implicated as underlying the V(D)J recombination and DNA double-strand break repair defects in the xrs-6 Chinese hamster ovary cell line. We now show that the mutation in theKu80gene involves a G to A transition 15 bp upstream of exon 2. This mutation creates a new splice acceptor site which results in the generation of a Ku80 transcript that cannot encode a functional product due a 13 nucleotide Insertion and a resulting frameshift.
