摘要


The anaphase-promoting complex/cyclosome (APC/C) is a cell-cycle-regulated essential E3 ubiquitin ligase; however, very little is known about its meiotic regulation. Here we show that fission yeast Mes1 is a substrate of the APC/C as well as an inhibitor, allowing autoregulation of the APC/C in meiosis. Both traits require a functional destruction box (D box) and KEN box. We show that Mes1 directly binds the WD40 domain of the Fizzy family of APC/C activators. Intriguingly, expression of nonubiquitylatable Mes1 blocks cells in metaphase I with high levels of APC/C substrates, suggesting that ubiquitylation of Mes1 is required for partial degradation of cyclin B in meiosis I by alleviating Mes1 inhibitory function. Consistently, a ternary complex, APC/C-Fizzy/Cdc20-Mes1, is stabilized by inhibiting Mes1 ubiquitylation. These results demonstrate that the fine-tuning of the APC/C activity, by a substrate that is also an inhibitor, is required for the precise coordination and transition through meiosis.
