摘要

减数分裂重组是通过一个特殊的途径进行的,该途径是由Spo11蛋白(古细菌拓扑异构酶VI的亲戚)制造的DNA双链断裂的形成和修复。本文综述了最近的研究,这些研究提供了对Spo11 DNA切割机制的见解,Spo11与断裂形成所需的其他蛋白质的功能相互作用,控制重组起始时间的机制。以及这些过程的进化守恒和分化。

Spo11 and the Formation of DNA Double-Strand Breaks in Meiosis.

Meiotic recombination is carried out through a specialized pathway for the formation and repair of DNA double-strand breaks made by the Spo11 protein, a relative of archaeal topoisomerase VI. This review summarizes recent studies that provide insight to the mechanism of DNA cleavage by Spo11, functional interactions of Spo11 with other proteins required for break formation, mechanisms that control the timing of recombination initiation, and evolutionary conservation and divergence of these processes.
