有丝分裂检查点确保染色体在子细胞之间平均分配,是防止染色体不稳定的主要机制,通常在非整倍体人类肿瘤中看到。ZW10和Rod在这个检查点中起着重要的作用。我们发现,在有丝分裂的人类细胞中,ZW10与Rod和Zwilch位于一个复合体中,而ZW10的另一个伙伴Zwint-1则是一个由Mis12和Ndc80-Hec1组成的结构着丝点组分的独立复合体的一部分。Zwint-1对于将ZW10招募到未附着的着丝点至关重要。利用人类细胞或爪蟾卵提取物的耗竭来证明ZW10复合物对于Mad1-Mad2复合物与未附着的着丝点的稳定结合至关重要。因此,ZW10作为外部着丝点核心结构元件和催化产生有丝分裂检查点衍生的“停止后期”抑制剂的组分之间的连接体。
The mitotic checkpoint ensures that chromosomes are divided equally between daughter cells and is a primary mechanism preventing the chromosome instability often seen in aneuploid human tumors. ZW10 and Rod play an essential role in this checkpoint. We show that in mitotic human cells ZW10 resides in a complex with Rod and Zwilch, whereas another ZW10 partner, Zwint-1, is part of a separate complex of structural kinetochore components including Mis12 and Ndc80–Hec1. Zwint-1 is critical for recruiting ZW10 to unattached kinetochores. Depletion from human cells or Xenopus egg extracts is used to demonstrate that the ZW10 complex is essential for stable binding of a Mad1–Mad2 complex to unattached kinetochores. Thus, ZW10 functions as a linker between the core structural elements of the outer kinetochore and components that catalyze generation of the mitotic checkpoint-derived “stop anaphase” inhibitor.
