Germ cells undergoing meiosis rely on an intricate network of surveillance mechanisms that govern the production of euploid gametes for successful sexual reproduction. These surveillance mechanisms are particularly crucial during meiotic prophase, when cells execute a highly orchestrated program of chromosome morphogenesis and recombination, which must be integrated with the meiotic cell division machinery to ensure the safe execution of meiosis. Dynamic protein phosphorylation, controlled by kinases and phosphatases, has emerged as one of the main signaling routes for providing readout and regulation of chromosomal and cellular behavior throughout meiotic prophase. In this review, we discuss common principles and provide detailed examples of how these phosphorylation events are employed to ensure faithful passage of chromosomes from one generation to the next.
进行减数分裂的生殖细胞依赖于一个复杂的监测机制网络,该网络控制整倍体配子的产生,以实现成功的有性生殖。这些监测机制在减数分裂前期尤为关键,此时细胞执行高度协调的染色体形态发生和重组程序,该程序必须与减数分裂细胞分裂机制整合,以确保减数分裂的安全进行。由激酶和磷酸酶控制的动态蛋白质磷酸化已成为在减数分裂前期提供染色体和细胞行为读数及调节的主要信号通路之一。在这篇综述中,我们讨论了共同原则,并提供了详细的例子来说明这些磷酸化事件是如何被用于确保染色体从上一代到下一代的忠实传递的。
