Members of this family are components of the mitotic spindle. It has been shown that Nuf2 from yeast is part of a complex called the Ndc80p complex [1]. This complex is thought to bind to the microtubules of the spindle. An arabidopsis protein has been included in this family that has previously not been identified as a member of this family, Swiss:Q9C953. The match is not strong, but in common with other members of this family contains coiled-coil to the C terminus of this region.
