During cell division, accurate distribution of the genome by the mitotic spindle requires that sister chromatids remain tethered until the right moment. Studies of an uncharacterized vertebrate protein, Sgo (Salic et al., 2004 [this issue of Cell]), reveal dual roles as a chromosome cohesion factor and a regulator of spindle microtubule dynamics.
在细胞分裂过程中,有丝分裂纺锤体精确分配基因组需要姐妹染色单体一直保持连接状态直至合适时机。对一种未被鉴定的脊椎动物蛋白Sgo(Salic等人,2004年[本期《细胞》杂志])的研究揭示了它作为染色体黏连因子和纺锤体微管动力学调节因子的双重作用。
