人类细胞具有RECQL1、BLm、WRN、RTS和RECQL5五个RECQ家族解旋酶,它们的缺陷导致癌症的易感性。本研究对这些RecQ家族解旋酶的功能进行了研究,获得了以下结果。BLM在DNA复制的最后阶段、复制DNA的分离和姐妹染色单体的聚集中起作用。RTS参与DNA复制和DNA双链断裂的修复。最后,RECQL1和RECQL5参与重组的早期阶段。
英文摘要
Human cells possess five RecQ family helicases, RECQL1, BLM, WRN, RTS, and RECQL5, whose defects cause a predisposition to cancer. In this study, functions of these RecQ family helicases were investigated and following results were obtained. BLM functions at the last stage of DNA replication, segregation of replicated DNA and sister chromatid cohesion. RTS is involved in DNA replication and repair of DNA double strand breaks. Finally, RECQL1 and RECQL5 are involved in early stages of recombination.
