休闲渔民在钓线上保持紧张,以防止上钩的鱼被释放。这个钓鱼者的把戏的一个分子版本,在动点操作,确保了有丝分裂的准确性:有丝分裂的纺锤体随机附着在染色体上,然后由于相对的微管施加在染色体上的张力,正确的双向连接得到稳定。不正确的附着物缺乏张力,是不稳定的,释放得很快,允许另一个双向的机会。通过张力稳定分子相互作用也发生在其他生理环境中,如细胞黏附、运动、止血和组织形态形成。在这里,我们回顾了动粒附着稳定的模型,并着眼于其他力激活系统的新兴模型。虽然有丝分裂领域的注意力主要集中在一种基于激酶的机制上,但多种机制可能共同作用以稳定适当的生物定向动点,一些支配其他张力敏感系统的原理也可能适用于动点。
Sport fishermen keep tension on their lines to prevent hooked fish from releasing. A molecular version of this angler’s trick, operating at kinetochores, ensures accuracy during mitosis: The mitotic spindle attaches randomly to chromosomes and then correctly bioriented attachments are stabilized due to the tension exerted on them by opposing microtubules. Incorrect attachments, which lack tension, are unstable and release quickly, allowing another chance for biorientation. Stabilization of molecular interactions by tension also occurs in other physiological contexts such as cell adhesion, motility, hemostasis, and tissue morphogenesis. Here we review models for the stabilization of kinetochore attachments with an eye toward emerging models for other force-activated systems. While attention in the mitosis field has focused mainly on one kinase-based mechanism, multiple mechanisms may act together to stabilize properly bioriented kinetochores and some principles governing other tension-sensitive systems may apply to kinetochores as well.
