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.	Domain

This domain is found in Nude C 80 (Ndc80) proteins which can be found in species such as Homo sapiens. Ndc80 protein complexes are a core component of the end-on attachment sites for kinetochore microtubules. Ndc80 is also known as Hec1, for highly expressed in cancer 1 [1].	Domain
