黏连蛋白是一种环状蛋白质复合物,它组织基因组,使其能够浓缩,表达,修复和传输。凝聚素最为人所知的是它在染色体分离中的作用,在S期,它提供了两个新复制的姐妹染色单体之间建立的凝聚力。这种内聚力使姐妹染色单体能够通过抵抗相反的拉力而正确地附着在纺锤体的微管上。一旦所有的染色体都正确地连接在一起,粘着蛋白就突然被破坏,从而在分裂后期触发姐妹染色单体向相反两极的平等分离。在这里,我们总结的分子功能和调节的粘着蛋白,其核心作用在有丝分裂过程中的染色体分离。黏连蛋白是一种环状蛋白质复合物,它组织基因组,使其能够浓缩,表达,修复和传输。在这本《引物》中,Makrantoni和马斯顿总结了粘着蛋白的分子功能和调节,这些功能和调节是粘着蛋白在有丝分裂期间染色体分离中的核心作用的基础。
Cohesin is a ring-shaped protein complex that organises the genome, enabling its condensation, expression, repair and transmission. Cohesin is best known for its role in chromosome segregation, where it provides the cohesion that is established between the two newly duplicated sister chromatids during S phase. This cohesion enables the proper attachment of sister chromatids to microtubules of the spindle by resisting their opposing pulling forces. Once all chromosomes are correctly attached, cohesin is abruptly destroyed, triggering the equal segregation of sister chromatids to opposite poles in anaphase. Here we summarise the molecular functions and regulation of cohesin that underlie its central role in chromosome segregation during mitosis. Cohesin is a ring-shaped protein complex that organises the genome, enabling its condensation, expression, repair and transmission. In this Primer, Makrantoni and Marston summarise the molecular functions and regulation of cohesin that underlie its central role in chromosome segregation during mitosis.
