后期促进复合物(APC/C)是一种保守的多亚基E3泛素(Ub)连接酶,在分裂和有丝分裂后的细胞中都有活性。它对生命的贡献在细胞分裂领域得到了很好的研究,其中APC/C位于控制细胞周期事件方向和时间的调节网络的中心。生物化学和结构工作揭示了APC/C亚基的整体组织,底物识别和Ub链起始和延伸的机制,以及有丝分裂过程中控制APC/C活性的检查点的分子机制。在这里,我们回顾这些最新的进展是如何改变我们对APC/C的理解。
The anaphase-promoting complex or cyclosome (APC/C) is a conserved, multisubunit E3 ubiquitin (Ub) ligase that is active both in dividing and in postmitotic cells. Its contributions to life are especially well studied in the domain of cell division, in which the APC/C lies at the epicenter of a regulatory network that controls the directionality and timing of cell cycle events. Biochemical and structural work is shedding light on the overall organization of APC/C subunits and on the mechanism of substrate recognition and Ub chain initiation and extension as well as on the molecular mechanisms of a checkpoint that seizes control of APC/C activity during mitosis. Here, we review how these recent advancements are modifying our understanding of the APC/C.
