中文摘要
今年,我们小组发表了9篇与DNA复制保真度有关的科学文章。我们发现,在真核细胞核DNA复制过程中掺入的核糖核苷酸容易形成双链DNA断裂,从而导致基因组不稳定。这些断裂是由于拓扑异构酶1切割DNA聚合酶epsilon结合的核糖核苷酸造成的,DNA聚合酶epsilon是主要的链复制酶。我们与其他人合作描述了DNA聚合酶Mu与核糖核苷酸结合的X射线晶体群,并表明第三种二价金属离子参与了DNA聚合酶Mu的DNA合成。我们还发表了六篇评论文章。
英文摘要
This year, our group published nine scientific articles related to DNA replication fidelity. We showed that ribonucleotides incorporated during eukaryotic nuclear DNA replication are subject to formation of double strand DNA breaks that result in genome instability. These breaks are due to topoisomerase 1 incision of ribonucleotides incorporated by DNA polymerase epsilon, the primarily leading strand replicase. We collaborated with others to describe the X ray crystal group of DNA polymerase mu bound to a ribonucleotide, and to show that a third divalent metal ion is involved in DNA synthesis by DNA polymerase mu. We also published six review articles.
