CC   -!- FUNCTION: Acts as a component of the essential kinetochore-associated
CC       Ndc80 complex, which is required for chromosome segregation and spindle
CC       checkpoint activity during meiosis and mitosis. Required for
CC       kinetochore integrity and the organization of stable microtubule
CC       binding sites in the outer plate of the kinetochore. Participates in
CC       SAC signaling that responds specifically to disruptions in spindle
CC       microtubule dynamics. The NDC80 complex synergistically enhances the
CC       affinity of the SKA1 complex for microtubules and may allow the NDC80
CC       complex to track depolymerizing microtubules.
CC       {ECO:0000250|UniProtKB:Q9HBM1, ECO:0000250|UniProtKB:Q9V3V7}.
CC   -!- SUBUNIT: Component of the Ndc80 complex, which is composed of Ndc80,
CC       Nuf2 and Spc25. {ECO:0000250|UniProtKB:Q9V3V7}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9V3V7}.
CC       Chromosome, centromere, kinetochore {ECO:0000250|UniProtKB:Q9V3V7}.
CC   -!- SIMILARITY: Belongs to the SPC25 family. {ECO:0000255}.
