Silva等人证明了不同的粘着蛋白复合物对于哺乳动物卵母细胞中的姐妹染色单体粘着和基因组折叠是必不可少的。Scc 1-cohesin是染色质环所必需的,而Rec 8-cohesin介导二价凝聚。Wapl介导的Scc 1-粘附素的释放是减数分裂I染色体分离所必需的,并促进整倍体卵子的产生。
Silva et al. demonstrate that distinct cohesin complexes are essential for sister chromatid cohesion and genome folding in mammalian oocytes. Scc1-cohesin is required for chromatin loops while Rec8-cohesin mediates bivalent cohesion. Wapl-mediated release of Scc1-cohesin is required for accurate meiosis I chromosome segregation and promotes production of euploid eggs.
