CC   -!- FUNCTION: Component of the SKA1 complex, a microtubule-binding
CC       subcomplex of the outer kinetochore that is essential for proper
CC       chromosome segregation (PubMed:19289083, PubMed:19360002,
CC       PubMed:23085020). The SKA1 complex is a direct component of the
CC       kinetochore-microtubule interface and directly associates with
CC       microtubules as oligomeric assemblies (PubMed:19289083,
CC       PubMed:19360002). The complex facilitates the processive movement of
CC       microspheres along a microtubule in a depolymerization-coupled manner
CC       (PubMed:19289083). In the complex, it mediates the microtubule-
CC       stimulated oligomerization (PubMed:19289083). Affinity for microtubules
CC       is synergistically enhanced in the presence of the ndc-80 complex and
CC       may allow the ndc-80 complex to track depolymerizing microtubules
CC       (PubMed:23085020). {ECO:0000269|PubMed:19289083,
CC       ECO:0000269|PubMed:19360002, ECO:0000269|PubMed:23085020}.
CC   -!- SUBUNIT: Component of the SKA1 complex, composed of SKA1, SKA2 and SKA3
CC       (PubMed:19289083, PubMed:19360002). The core SKA1 complex is composed
CC       of 2 SKA1-SKA2 heterodimers, each heterodimer interacting with a
CC       molecule of the SKA3 homodimer (PubMed:19289083, PubMed:19360002). The
CC       core SKA1 complex associates with microtubules and forms oligomeric
CC       assemblies (PubMed:19289083, PubMed:19360002, PubMed:23085020).
CC       Interacts with SKA1; the interaction is direct (PubMed:19289083,
CC       PubMed:23085020). {ECO:0000269|PubMed:19289083,

CC       Note=Localizes to the outer kinetochore and spindle microtubules during
CC       mitosis in a NDC80 complex-dependent manner.
