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

This is the C-terminal segment of Stu2, which binds the four-way junction of the Ndc80 complex (Ndc80c). This interaction is crucial for association of Stu2 with kinetochores, that when it is compromised, there is impairment in cell viability, biorientation defects and delay in cell cycle progression [1].
