Loss of sister-chromatid cohesion triggers chromosome segregation. Several recent reports show that the protease Esp1 cleaves the cohesin subunit Scc1/Mcd1 to induce sister-chromatid segregation in yeast and vertebrates. This finding indicates that cohesin cleavage may control sister-chromatid separation in all vertebrates.
姐妹染色单体黏连的丧失引发染色体分离。最近的几项报告表明,蛋白酶Esp1切割黏连蛋白亚基Scc1/Mcd1,以在酵母和脊椎动物中诱导姐妹染色单体分离。这一发现表明,黏连蛋白的切割可能在所有脊椎动物中控制姐妹染色单体的分离。
