CSFExtractPrepforSpindleAssembly
This protocol is essentially as described by Murray (1991), Cell Cycle Extracts. In Methods in Cell Biology, B.K. Kay and B. Peng, eds. (San Diego: Academic Press), pp. 581-605. I've included a protocol which emphasizes the points that we find are most important for obtaining good CSF extracts that are competent for CSF spindle assembly and for cycled spindle assembly. The indicated buffer amounts are sufficient ......阅读全文

细胞周期纺锤体组装检查点的概念
纺锤体组装检查点（the spindle-assembly checkpoint, SAC）可以阻止染色体分离，直到姐妹染色单体（sister chromatid）正确地连接于有丝分裂纺锤体上。这一作用是通过使CDC20（也叫做Slp1或Fizzy）失活完成的，它是泛素连接酶分裂后期促进复合体或循环
