RT "Mitch a rapidly evolving component of the Ndc80 kinetochore complex
RT required for correct chromosome segregation in Drosophila.";
RL J. Cell Sci. 120:3522-3533(2007).
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}.
