Protein Domain : Spindle and kinetochore-associated protein 2 IPR026762

Type	Family
Description	Spindle and kinetochore-associated protein 2 (Ska2) is a component of the SKA1 complex (consists of Ska1, Ska2, and Ska3/Rama1), a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation [ ]. It is required for timely anaphase onset during mitosis, when chromosomes undergo bipolar attachment on spindle microtubules leading to silencing of the spindle checkpoint []. The SKA1 complex is a direct component of the kinetochore-microtubule interface and directly associates with microtubules as oligomeric assemblies. The complex facilitates the processive movement of microspheres along a microtubule in a depolymerisation-coupled manner. In the complex, it is required for SKA1 localisation [ ].
