Acts as a component of the NMS (Ndc80-MIND-Spc7) super complex which has a role in kinetochore function during late meiotic prophase and throughout the mitotic cell cycle. Essential for chromosome segregation and bipolar sister chromatid association. Required for kinetochore targeting of MIND, but not Ndc80 complex components. Component of the NMS super complex which consists of mis12, mis13, mis14, ndc80, nnf1, nuf2, sos7, spc7, spc24 and spc25. Interacts (via C-terminus) directly with spc7 (via C-terminus).
