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. Required for kinetochore integrity and the
CC       organization of stable microtubule binding sites in the outer plate of
CC       the kinetochore. 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:Q9BZD4}.
CC   -!- SUBUNIT: Component of the NDC80 complex, which is composed of ndc80,
CC       cdca1, spbc24 and spbc25. The NDC80 complex interacts with mis12 and
CC       zwint (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome, centromere,
CC       kinetochore {ECO:0000250}. Note=Localizes to kinetochores from late
CC       prophase to anaphase. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the NUF2 family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAH72877.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence. Potential poly-A sequence.; Evidence={ECO:0000305};
CC       Sequence=AAI00208.1; Type=Erroneous initiation; Evidence={ECO:0000305};
