Polo-like kinase 1 (Plk1) is a key regulator of cell division in eukaryotic cells. In this short review, we briefly summarized the well-established functions modulated by Plk1 during mitosis. Beyond mitosis, we focused mainly on the unexpected processes in which Plk1 emerges as a critical player, including microtubule dynamics, DNA replication, chromosome dynamics, p53 regulation, and recovery from the G2 DNA-damage checkpoint. Our discussion is mainly based on the critical substrates targeted by Plk1 during these cellular events and the functional significance associated with each phosphorylation event.
丝氨酸/苏氨酸激酶 1(Plk1)是真核细胞细胞分裂的关键调节因子。在这篇简短的综述中,我们简要总结了 Plk1 在有丝分裂过程中调节的已确立功能。除了有丝分裂,我们主要关注 Plk1 作为关键参与者出现的意外过程,包括微管动力学、DNA 复制、染色体动力学、p53 调节和从 G2 DNA 损伤检查点恢复。我们的讨论主要基于在这些细胞事件中 Plk1 靶向的关键底物以及与每个磷酸化事件相关的功能意义。
