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.
